摘要：

The electron-withdrawing SO2CF3 substituent of Cp(CO)(2)Re=C(Tol)(C equivalent to CC6H4-p-SO2CF3) (1d) greatly accelerates rearrangement via a [1,3]-rhenium shift. The [1,3]-rhenium shift is proposed to proceed via an 18-electron dehydrometallacyclobutadiene intermediate formed by alkyne coordination concerted with an eta (5)-eta (3) CP ring slip.
