Cycloaddition and C-S Bond Cleavage Processes in Reactions of Heterometallic Phosphinidene-Bridged MoRe and MoMn Complexes with Alkynes and Phenyl Isothiocyanate.

ABSTRACT: Reactions of [MoReCp(μ-PMes*)(CO)₆] with internal alkynes RC≡CR yielded the phosphapropenylidene-bridged complexes [MoReCp(μ-κ²_P,C:η³-PMes*CRCR)(CO)₅] (Mes* = 2,4,6-C₆H₂^tBu₃; R = CO₂Me, Ph). Terminal alkynes HC≡CR¹ gave mixtures of isomers [MoReCp(μ-κ²_P,C:η³-PMes*CHCR¹)(CO)₅] and [MoReCp(μ-κ²_P,C:η³-PMes*CR¹CH)(CO)₅], with the first isomer being major (R¹ = CO₂Me) or unique (R¹ = ^tBu), indicating the relevance of steric repulsions during the [2 + 2] cycloaddition step between Mo=P and C≡C bonds in these rea
