摘要:
AbstractThe reaction of Me3SiCH2I with [Pd(ItBu)2] (ItBu = 1,3‐di‐tert‐butyl‐imidazol‐2‐ylidene) results, not in simple oxidative addition, but in carbon–silicon bond activation and formation of [Pd(Me3Si)(ItBu)(μ‐I)]2 (2) and [Pd(CH2ItBu)I2] (3). The zwitterionic nature of the latter has been confirmed by DFT studies, and a possible mechanism for the formation of these two unexpected products is presented. Complex 2 has also been synthesised independently by the direct oxidative addition of Me3SiI to [Pd(ItBu)2].(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
