“…Siloxide complexes containing a rhodium center have been widely investigated because of their high catalytic activity in reactions such as hydrosilylation and hydroformylation. 27–44 However, most of the rhodium siloxide complexes reported to date are supported by monodentate siloxide ligands. 34–44 To the best of our knowledge, only two examples of rhodium complexes bearing multidentate siloxide ligands, {Rh(COD)} 2 {μ-(OSiPh 2 ) 2 O} (COD = cyclooctadiene) and {Rh(CO) 2 } 2 {μ-(OSiPh 2 ) 2 O}, have been so far reported.…”

Rhodium siloxide complexes have been used as homogeneous catalysts and model compounds for silica-supported metal catalysts. However, rhodium complexes with multidentate siloxide ligands have rarely been prepared. In this study,...

The pro-ligands 1,8-bis(di-R-phosphinomethyl)-2,3-dihydroperimidine (RH2Pm, R = phenyl, cyclohexyl) react with [RhCl(CE)(PPh3)2] (E = O, S) to afford the bimetallic complexes [RhCl(CE)(-RH2Pm)]2 (E = O, S). Upon heating, these species undergo...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
