Heterobimetallic cycloheptatrienyl and cycloheptatrienylidene complexes

Abstract

The heterobimetallic µ-(η¹:η⁶-1,3,5-cycloheptatrien-2-yl) complex 4 is obtained from 2-trimethylstannyl-1,3,5-cycloheptatriene 2 and [CpFe(CO)₂Br] followed by reaction with [(EtCN)₃Cr(CO)₃]; hydride abstraction results in the formation of the first heterobimetallic cycloheptatrienylidene (CHT) complex [CpFe(CO)₂{µ-(η¹:η⁷-CHT)}Cr(CO)₃]BF₄ 5; the crystal structure of 4 is reported.
