The reaction of Me 3 SiCH 2 I with [Pd(ItBu) 2 ] (ItBu = 1,3-ditert-butyl-imidazol-2-ylidene) results, not in simple oxidative addition, but in carbon-silicon bond activation and formation of [Pd(Me 3 Si)(ItBu)(µ-I)] 2 (2) and [Pd(CH 2 ItBu)I 2 ] (3). The zwitterionic nature of the latter has been confirmed by DFT studies, and a possible mechanism for the formation of these
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.
