prepared in 80–92% yields from (η-C5H5)Re(NO)(CO)Cl using an excess of the arylcopper reagents RCu. Reactions of (η-C5H5)Re(NO)(CO)X (X = Cl, Br, I) with phenylmagnesium bromide or phenyllithium afford the phenylrhenium compound in low yield or not at all, and an explanation is offered for this. Optimum reaction conditions, sources of the arylcopper reagent, and other variables in the syntheses have been
