Insertion of alkynes into molybdenum-phosphine and molybdenum-carbon bonds. X-ray structure of the phosphonium-alkylidene complex [MoO{C(Ph)CHC(Ph) CH 2 PMe 2 Ph}(SC 6H 2iPr 3−2,4,6) 3

Abstract

Treatment of [MoH(SC 6H 2 iPr 3−2,4,6) 3(PMe 2Ph) 2] with PhCCH in tetrahydrofuran (THF) followed by MeOH gives the phosphonium-alkylidene complex [MoO{C(Ph)CHC(Ph)CH 2PMe 2Ph}(SC 6H 2 iPr 3−2,4,6) 3], whose X-ray crystal structure has been determined.
