This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium(II) complex CpTiCl(dmpe)$sb2$ is prepared by reducing (CpTiCl$sb2)sb{rm x}$ with n-butyllithium in the presence of 1,2-bis(dimethylphosphino)ethane (dmpe). Subsequent treatment with methyllithium or n-butyllithium affords CpTiMe(dmpe)$sb2$ and CpTiH(dmpe)$sb2$, respectively. The crystal structures of CpTiX(dmpe)$sb2$ (X = Cl, Me, H) show unusually long metal ligand distances. Analogous treatment of (Cp$sp*$Ti(BH$sb4$)Cl) $sb2$ with n-butyllithium affords Cp$sp*$Ti(BH$sb4$)(PP), where PP is dmpe or (t-butyl)tris(dimethylphosphino-methyl)silane. All of these titanium(II) complexes catalyze oligomerization of ethylene to 1-butene, 2-ethyl-1-butene, and 3-methyl-1-pentene, probably via metallacyclopentane intermediates. Oxidations of the neutral titanium(II) complexes with 1,1$spprime$-dimethylferrocinium salts afford the first examples of cationic alkyltitanium(III) complexes: (CpTiX(dmpe)$sb2rbrack$ BAr$sb4,$ where Ar = Ph or 3,5-(CF$sb3)sb2$C$sb6$H$sb3$ (FPB). Two other complexes, (TiMe$rm sb2(dmpe)sb2rbrack$ FPB and (Cp$sp*$Ti(BH$sb4$)(dmpe)) FPB, have been prepared by oxidation of the corresponding titanium(II) species. Crystallographic studies of (CpTiH(dmpe)$sb2$) FPB, (TiMe$sb2$(dmpe)$sb2$) FPB, and (Cp$sp*$Ti(BH$sb4$)(dmpe)) FPB reveal that the titanium(III) cations show a lengthening of the Ti-P bond distances owing to a decrease in metal-ligand $pi$-back-bonding. The cationic titanium(III) alkyls neither oligomerize nor polymerize ethylene. Treatment of Rh(hfac)(CH$sb2$=CH$sb2)sb2$ (hfac = hexafluoroacetylacetonate) with vinyl-trimethylsilane, 1,2-bis(trimethylsilyl)acetylene, Cu(hfac)(COT), or PMe$sb3$ affords a series of new complexes. High purity rhodium films have been deposited at 200-300 $spcirc$C using Rh(hfac)(CH$sb2$ = CH$sb2)sb2$ as a CVD precursor. The deposition occurs via the disproportionation reaction 3 Rh(hfac)(alkene)$sb2$ $longrightarrow$ 2 Rh + Rh(hfac)$sb3$ + 6 alkene. Ultra high vacuum studies show that Rh(hfac)(CH$sb2$ = CH$sb2)sb2$ adsorbs molecularly on copper surfaces up to 130 K. The hfac groups are oriented perpendicular to the surface at 220 K. Reduction of rhodium(I) occurs at approximately 300 K. Decomposition of surface-bound hfac groups occurs at higher temperatures. This process does not occur under CVD conditions owing to the higher coverages characteristic of this process, which favor bimolecular reactions that lead to the assembly of the observed Rh(hfac)$sb3$ product.

This book was released on 2004-06-21 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-arene p-complexes show a rich and varied chemistry. The metal adds a third dimension to the planar aromatic compounds and coordination of a metal to an arene thus not only altering the reactivity of ring-carbons and substituents but also makes possible reactions that lead to chiral non-racemic products. This book, organized in nine chapters and written by leading scientists in the field provides the reader with an up-to-date treatise on the subject organized according to reaction type and use. It covers the wide spectrum of arene activation: from the electrophilic activation of h6-bound areneï⿬ by p-Lewis acid metal complex fragments, to reactions of nucleophilic h2-coordinated arene complexes. The preparation of complexes is detailed, as are the scope, limitations and challenges of reactions in contemporary p-arene metal chemistry with special attention given to asymmetric transformations. The emphasis of the book is on transformations of interest to organic synthesis and on the use of the complexes as catalysts or as chiral ligands. The book is written for academic and industrial researchers in organic, organometallic, and inorganic chemistry as well as for advanced chemistry students
