DETECTION OF A NOVEL INTERMEDIATE IN THE ADDITION OF THIOLS TO OSMIUM CARBONYL CLUSTERS

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.
