Available in PDF, EPUB and Kindle. Book excerpt: Condensation of Ph2PCH2OH with a range of polyaromatic substituted secondary amines afforded a new set of hybrid phosphine ligands of the type {RCH2N(CH2PPh2)CH2}2 and RCH2N(CH2PPh2)CH2CH3 (R = various planar aromatic groups). The coordination chemistry of these new mono and bidentate ligands towards a range of transition metal centres including Mo(0), Au(I), Rh(I), Ni(II), Pd(II), Pt(II) and Ru(II) was investigated. Ditertiary phosphines of the form {RCH2N(CH2PPh2)CH2}2 were found to be capable of bridging two transition metal centres in addition to forming rare examples of nine membered cis and trans chelate complexes. Single crystal X ray analysis of these coordination compounds revealed several types of inter and intramolecular packing interactions (including a C H Pt interaction and slipped intermolecular π ... π stacking), and also confirmed the rare trans diphosphine coordination mode. Fluorescent emission measurements have been undertaken on these new tertiary phosphines and their coordination compounds, and these luminescent properties are discussed. A preliminary investigation into the chemosensory behaviour of selected compounds has been undertaken. Using RPCH2OH (RP = Ph2P, Cy2P or AdP = 1,3,5,7, tetramethyl 2,4,8 trioxa 6 phosphaadamantane) as a versatile precursor, a range of ferrocenyl (Fc) tertiary phosphines have been prepared from a selection of primary and secondary amines. The coordination chemistry of these new mono and bidentate ligands towards several transition metal centres including Cr(0), Mo(0), Au(I), Rh(I), Ru(II), Pd(II) and Pt(II) was investigated. In particular, the previous chemistry was expanded to prepare several new diferrocenyl phosphines of the form {FcCH2N(CH2PR)CH2}2. In a similar manner to their polyaromatic counterparts, these ditertiary phosphines were found to be capable of coordination through both bridging and cis-/ trans-chelating modes. Notably, single crystal X ray analysis was used to confirm the formation of an extr.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of different catalytic reactions applied to the activation of chemical bonds. Each of the seven chapters covers key C-X classes where carbon is combined with another element: chlorine, fluorine, nitrogen, sulfur, oxygen, hydrogen, and carbon. The first part of the book discusses homogeneous catalysis in the activation and transformation of C-Cl and C-F, highlighting their basic activation modes, cross-coupling, and intensive mechanisms. The second part of the book focuses on C-N, C-S, and C-O bonds, mentioning their catalytic pathways. Finally, C-H and C-C bonds, their activation, chemical transformations, and applicability are covered. Overall, the book presents methodologies that can be applied to the efficient synthesis of drug molecules and fine chemicals. Through their presentation, the authors show that synthetic chemistry can be done in greener ways that limit hazards and pollution.

Download or read book Chiral Ligands written by Montserrat Diéguez and published by CRC Press. This book was released on 2021-05-12 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many new drugs on the market are chiral compounds, that is, they can exist in two non-superimposable mirror-image forms. Asymmetric catalysis encompasses a large variety of processes for obtaining such compounds. The performance of the catalyst in those processes largely depends on the ligand that makes up the catalyst. This book describes the most relevant ligand libraries for some key processes, including an overview of the state of art and the key mechanistic aspects that favor a high catalytic performance. Key Features: The book presents historical content from the time of discovery for each family of ligands. Provides a description of the synthetic route and the ligand library's application in various catalytic asymmetric reactions Suitable as supplementary reading for courses targeting the design, synthesis and application of chiral catalysts, asymmetric catalysis and sustainable production Edited by a distinguished scientist in the field, the book has a diverse audience including research groups in homogeneous catalysis, particularly asymmetric transformations
