Chiral Ligand Design: A Bidentate Ligand Incorporating an Acyclic Phosphaalkeneiridiumligand designNP-ligandsphosphaalkenesphosphorusSince Becker's landmark discovery of the first isolable phosphaalkene just over three decades ago, there has been a growing interest in low coordinate multiply bonded ...
Achieving an efficient catalyst in the ATRP system with a simple design, preparation from available materials, and high recyclability is a significant challenging issue. To attain the goal, herein, we used chitosan (CS)-modified cellulose filter paper (FP) as a green support for the synthesis of...
The structure of Ti(MeCp)2(S3). Numerous examples and structural characterization of complexes containing the [S4]2– ligand exist. Typically within these compounds, the S42- anion acts as a bidentate ligand and adopts either an ‘envelope’ or a ‘half-chair’-type conformation. Metal atoms...
232 Asymmetric catalysis is usually a strategy where a transition metal complex containing a chiral ligand catalyses the transformation of a prochiral substrate into one enantiomer as a major product.

The reaction of 1-(2-bromophenyl)-4-phenyl-1H-1,2,3-triazole (1) with Ph2PCl yielded bisphosphine, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole (2). Bisphosphine 2 exhibits ambidentate character in either the κ2-P,N or κ2-P,P coordinatio...

Crystal contacts are observed between the C-terminal tail of one molecule and the C-terminal amphipathic groove of a neighbouring one, resembling interactions between ligand and proteins containing tetratricopeptide-like repeats. Conclusions The structure of antigen c5321 presents a mode of stabilization ...
Solvias has also disclosed a bidentate ligand family possessing a SPO moiety, in which chirality at phosphorus is used as the stereochemical control element.166 These ligands are reported for use in asymmetric hydrogenation, and enantiomer separation was again achieved by chiral HPLC. In the example...
Thus, it is difficult for the incoming monomer to displace the solvent, especially for DME which is a bidentate ligand. In this case, an alternative mechanism II is more likely (Scheme 8). Here, the monomer vinyl group directly attacks the carbanion without coordinating with the shielded ...
