This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book excerpt: This is the second set of Handbook of Porphyrin Science.Porphyrins, phthalocyanines and their numerous analogues and derivatives are materials of tremendous importance in chemistry, materials science, physics, biology and medicine. They are the red color in blood (heme) and the green in leaves (chlorophyll); they are also excellent ligands that can coordinate with almost every metal in the Periodic Table. Grounded in natural systems, porphyrins are incredibly versatile and can be modified in many ways; each new modification yields derivatives, demonstrating new chemistry, physics and biology, with a vast array of medicinal and technical applications.As porphyrins are currently employed as platforms for study of theoretical principles and applications in a wide variety of fields, the Handbook of Porphyrin Science represents a timely ongoing series dealing in detail with the synthesis, chemistry, physicochemical and medical properties and applications of polypyrrole macrocycles. Professors Karl Kadish, Kevin Smith and Roger Guilard are internationally recognized experts in the research field of porphyrins, each having his own separate area of expertise in the field. Between them, they have published over 1500 peer-reviewed papers and edited more than three dozen books on diverse topics of porphyrins and phthalocyanines. In assembling the new volumes of this unique Handbook, they have selected and attracted the very best scientists in each sub-discipline as contributing authors.This Handbook will prove to be a modern authoritative treatise on the subject as it is a collection of up-to-date works by world-renowned experts in the field. Complete with hundreds of figures, tables and structural formulas, and thousands of literature citations, all researchers and graduate students in this field will find the Handbook of Porphyrin Science an essential, major reference source for many years to come.

Abstract: Abstract of thesis entitled SYNTHESIS, STRUCTURES AND SPECTROSCOPIC PROPERTIES OF PRIMARY AND SECONDARY PHOSPHINE COMPLEXES OF IRON, RUTHENIUM AND OSMIUM PORPHYRINS Submitted by XIE JIN For the degree of Doctor of Philosophy at The University of Hong Kong in Oct 2007 Primary and secondary phosphine complexes of transition metals are of fundamental importance in metal-mediated P-H bond functionalization, phosphido/phosphinidene formation, and have applications in materials science. This thesis mainly describes the first isolation of primary and secondary phosphine complexes of a metalloporphyrin, along with their spectral, structural, and redox properties. The reactivity of primary and secondary phosphines coordinated to metalloporphyrins, particularly their hydrophosphination reactions with C=C bonds, is included. Investigations on the attempted approach to metal primary phosphine complexes bearing a pentapyridyl ligand (PY5) are also included. Ruthenium and osmium porphyrins form isolable complexes with primary and II secondary phosphines. Complexes [Ru (por)(PH Ph )] and n 3-n 2 II II [Os (por)(CO)(PH Ph )] (n = 1, 2) were prepared from reaction of [M (por)(CO)] n 3-n VI (M = Ru, Os) with excess PH Ph or PHPh . Reaction of [Os (por)O ] with PHPh 2 2 2 2 II mainly generated [Os (por){P(OH)Ph }(PHPh )], with concomitant formation of 2 2 II minor amounts of [Os (por){P(OH)Ph } ]. The bis-(primary phosphine) complex 2 2 II [Ru (F -tpp)(PH Ph)] is strikingly stable toward air and features reversible 20 2 2 +/0 Ru(II)/Ru(III) oxidation couple at E = 0.39 V vs Cp Fe . NMR spectrum 1/2 2 simulation revealed a strong coupling between the trans P nuclei in II 2 2 [Ru (por)(PH Ph ) ] (n = 1, 2; J ≈ 500 Hz). A J value of 467 Hz was directly n 3-n 2 PP PP 31 II obtained from the proton-decoupled P NMR spectrum of [Os (F - 20 tpp){P(OH)Ph }(PHPh )], which is much larger than that observed for the trans 2 2 phosphines in a non-porphyrin osmium phosphine complex. A one-pot synthesis of metal primary phosphine complexes from user-friendly O=PClR and PClR has been realized by treating these precursors with 2 2 II [Ru (por)(CO)] and LiAlH, leading to the isolation of primary alkylphosphine II complexes of ruthenium porphyrins, [Ru (por)(PH R) ] (por = ttp, 4-MeO-ttp, F -tpp; 2 2 20 t sec R = Ad, Bu, Bu), which are the first examples of primary alkylphosphine complexes of ruthenium. II Reactions of [Ru (F -tpp)(PH Ph ) ] (n = 1, 2) with CH =CHR (R = CO Et, 20 n 3-n 2 2 2 t II CN) in the presence of BuOK afforded [Ru (F -tpp){P(CH CH R) Ph } ] in high 20 2 2 n 3-n 2 yields. This is the first observation of alkene hydrophosphination by primary/secondary phosphines coordinated to a metalloporphyrin. The reactions of III [Fe (por)Cl] (por = F -tpp, 2,6-Cl tpp) with Na S O followed by treatment with 20 2 2 2 4 excess PH Ph, PHPh, or PH Ad led to the isolation of the first examples of iron 2 2 2 porphyrin complexes of primary and secondary phosphines, of which the primary phosphine complexes underwent partial dissociation in solutions at room temperature. Treatment of PY5 (or PY5-OH) with Ag(p-MeC H SO), AgNO, or 6 4 3 3 [Cu(MeCN) ]PF resulted in the isolation of [Ag (L) ]X (L = PY5 or PY5-OH, X = 4 6 2 2 2 - - I p-MeC H SO or NO ) and [Cu (PY5)(MeCN)]PF, which adopt two types of 6 4 3 3 6
