Detection of a novel intermediate in the addition of thiols to osmium carbonyl clusters

Abstract

Spectroscopic studies of the reaction of [Os₃(CO)₁₁MeCN)] with para-thiocresol to form [Os₃(µ-H)(CO)₁₀(µ-SC₆H₄Me-p)] indicate that the reaction proceeds via a two-step consecutive process involving the intermediate [Os₃(CO)₁₁-(MeC₆H₄SH-p)], in which there is an agostic Os–H–S interaction.
