Abstract The reaction of Me 3 SiCH 2 I with [Pd(I t Bu) 2 ] (I t Bu = 1,3‐di‐ tert ‐butyl‐imidazol‐2‐ylidene) results, not in simple oxidative addition, but in carbon–silicon bond activation and formation of [Pd(Me 3 Si)(I t Bu)(μ‐I)] 2 ( 2 ) and [Pd(CH 2 I t Bu)I 2 ] ( 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 Me 3 SiI to [Pd(I t Bu) 2 ].(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
