Book Description
Over the last 60 years the increasing knowledge of transition metal chemistry has resulted in an enormous advance of homogeneous catalysis as an essential tool in both academic and industrial fields. Remarkably, phosphorus(III) donor ligands have played an important role in several of the acknowledged catalytic reactions. The positive effects of phosphine ligands in transition metal homogeneous catalysis have contributed largely to the evolution of the field into an indispensable tool in organic synthesis and the industrial production of chemicals. This book aims to address the design and synthesis of a comprehensive compilation of P(III) ligands for homogeneous catalysis. It not only focuses on the well-known traditional ligands that have been explored by catalysis researchers, but also includes promising ligand types that have traditionally been ignored mainly because of their challenging synthesis. Topics covered include ligand effects in homogeneous catalysis and rational catalyst design, P-stereogenic ligands, calixarenes, supramolecular approaches, solid phase synthesis, biological approaches, and solubility and separation. Ligand families covered in this book include phosphine, diphosphine, phosphite, diphosphite, phosphoramidite, phosphonite, phosphinite, phosphole, phosphinine, phosphinidenene, phosphaalkenes, phosphaalkynes, P-chiral ligands, and cage ligands. Each ligand class is accompanied by detailed and reliable synthetic procedures. Often the rate limiting step in the application of ligands in catalysis is the synthesis of the ligands themselves, which can often be very challenging and time consuming. This book will provide helpful advice as to the accessibility of ligands as well as their synthesis, thereby allowing researchers to make a more informed choice. Phosphorus(III) Ligands in Homogeneous Catalysis: Design and Synthesis is an essential overview of this important class of catalysts for academic and industrial researchers working in catalyst development, organometallic and synthetic chemistry.

Book Description
The organometallic chemistry of the early first-row metals has been extended through the use of a new tridentate phosphine ligand, Bu$\sp{\rm t}$Si(CH$\sb2$PMe$\sb2$)$\sb3$, or "trimpsi". The starting materials (trimpsi)TiCl$\sb3$(thf), (trimpsi)VCl$\sb3$(thf), (trimpsi)CrCl$\sb3$, and (trimpsi)ZrCl$\sb4$(dme) have been used to prepare new carbonyl, arene, and alkyl complexes of the early transition metals.

Book Description
The polydentate, water-soluble bisphosphines $\rm (HOH\sb2C)P(CH\sb2)\sb{X}S(CH\sb2)\sb{Y}S(CH\sb2)\sb{X}P(CH \sb2OH)\sb2$ (X = 2, Y = 3, 3; X = 2, Y = 4, 9; X = 3, Y = 3, 12), $\rm (HOH\sb2C)P(CH\sb2)\sb2SC\sb6H\sb4S(CH\sb2)\sb2P(CH\sb2OH)\sb2$ (6), $\rm(HOH\sb2C)P(CH\sb2)\sb2P(C\sb6H\sb5)(CH\sb2)\sb2P(CH\sb2OH)\sb2$ (15), and $\rm(HOH\sb2C)P(CH\sb2)\sb2(CH\sb3)N (CH\sb2)\sb2N(CH\sb3)(CH\sb2)\sb2P(CH\sb2OH)\sb2$ (18), were synthesized in near quantitative yields by formylation of the appropriate phosphine hydrides in the presence of formaldehyde in oxygen-free ethanol. The reactions of 3 and 6, in aqueous solution, with (Pt(COD)) (Cl)$\sb2$ and $\rm\lbrack Pd(C\sb6H\sb5CN)\sb2\rbrack (Cl)\sb2,$ in methylene chloride, produced the water-soluble Pt(II)- and Pd(II)-complexes 19-22 in near quantitative yields. The reactions of 3, 9, and 12 with $\rm \lbrack ReO\sb2(C\sb5H\sb5N)\sb4\rbrack (Cl), $ in refluxing water, provided the Re(V)-complexes 23-25 in excellent yields. The reactions of 15, in aqueous solution, with $\rm\lbrack Pt(COD)\rbrack (Cl)\sb2,\ \lbrack Pd(C\sb6H\sb5CN)\sb2\rbrack (Cl)\sb2,\ \lbrack RhCl(1,5$-$\rm C\sb8H\sb{12})\rbrack\sb2,$ or $\rm\lbrack ReO\sb2\rbrack(PPh\sb3)\sb2\rbrack, $ in methylene chloride, provided for metallic complexes 26-30 in near quantitative yield. X-ray crystallographic analysis of compounds 20, 23, 24, and 25 established the molecular constitution of the metallic complexes. All of the compounds were characterized by $\sp1$H, $\sp{13}$C and $\sp{31}$p NMR spectroscopy, FABMS, and C and H analysis. Radiochemical in vitro investigations of 3 and 12 with technetium-99m provided evidence for the formation of complexes that were stable over a wide range of pH in excess of 24 hours. In vivo biodistribution analyses of the $\rm\sp{99m}Tc$-complexes in Sprague-Dawley rats provided for evidence of efficient clearance of the complexes at 2 hours post-injection via either the renal-urinary or hepatobiliary pathways. The results of these studies demonstrate the potential utility of thioether-functionalized, water-soluble, bisphosphines as bifunctional chelating agents for the labeling of specific biomolecules in nuclear medicinal applications.
