Abstract
The reaction of thiophene with the rhodium compound [TpRh(C2H4)(PMe(3 ))] (1a; Tp = hydrotris-(3,5-dimethyl-1-pyrazolyl)borate) leads to a mixture of the C-H an C-S activation products [TpRh(H)(2-C4H3S)(PMe(3 ))] (2a) and [TpRh(CHCHCHCHS)(PMe(3))] (3a), respectively. In contras t to previous observations, the former is the thermodynamically prefer red isomer. For the PEt(3) derivative [TpRh(C2H4)(PEt(3))] (1b), an e ven higher selectively toward C-H activation is observed.
