Reaction of Cyano Metal Acids NCAuCNH, (NC)4Pt(CNH)2, (NC)2M(CNH)4 (M = Fe, Ru, Os) and Co[bis(dimethylglyoximato)](CN)CNH with Epoxides: 2-Hydroxyalkylisocyanide and Oxazolidine-2-ylidene Metal Complexes

Abstract

NCAuCNH reacts with expoxides to give oxazolidine-2-ylidene (2) and 2-hydroxyalkyl complexes (3), respectively. Complexes with cyclic carbene ligands [XXX] (5) and [XXX] (7) are formed from the corresponding isocyanic metal compounds and oxiranes. 5b has been characterized by crystal structure determination. Ring opening of phenyloxirane occurs at the phenyl substituted carbon atom. (NC)2M(CNH)4 (M = Fe, Ru, Os) and oxirane yield mixtures of [XXX] and [XXX].
