摘要：

The reaction of thiophene with the rhodium compound [Tp*Rh(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 [Tp*Rh(H)(2-C4H3S)(PMe(3))] (2a) and [Tp*Rh(CHCHCHCHS)(PMe(3))] (3a), respectively. In contrast to previous observations, the former is the thermodynamically preferred isomer. For the PEt(3) derivative [Tp*Rh(C2H4)(PEt(3))] (1b), an even higher selectively toward C-H activation is observed.
