Abstract

Title full: Molybdenum promoted alkyne dimerisation leading to novel metallacycles: The crystal and molecular structures of prone-[Mo{?4-C(CF 3)C(CF3)C(Me)C(CO2Me)(SC6F 5)}(CF3C=CCF3)(?5-C 5H5)] and supine-[Mo{?4-C(CF 3)(SC6F5)C(CF3)C(Ph)C(Ph)}-(CF 3C=CCF3)(?5-C5H 5)]. Reactions of alkynes with [MoSC6F5(CF 3C=CCF3)2(?5-C 5H5)] 1 gives the novel prone ?4-butadienyl complex [Mo{?4-C(CF3)C(CF3)C(R')C(R) (SC6F5)}(CF3C=CCF3) (?5-C5H5)], which undergoes isomerisation via an ?2-vinyl intermediate to the supine isomer followed by a novel 1,4-thiolate migration to give supine-[Mo{?4-C(CF 3)(SC6F5)C(CF3)C(R)C(R')} (CF3=CCF3)(?5-C5H 5)].
