Web一站式科研服务平台. 学术工具. 文档翻译; 收录引证; 论文查重; 文档转换 WebInvestigations on the mechanism of formation of phosphinito Pt I complexes (carried out also employing NaOtBu and NaOPh as oxygenated bases) show that the first two steps of the overall reaction are the metathesis leading to cis-Pt(OR) 2 (PHCy 2) 2 and the subsequent formation of terminal phosphido complexes through ROH elimination.

WebFurther investigations on halide effects were performed notably by using a cationic ruthenacycle which was found to be an intermediate for the reaction. In order to rationalize the role played by the phosphinous acid, a mechanism involving a concerted metallation deprotonation favored by a phosphinito species has been proposed.
