The addition reactions of α-ferrocenylcarbenes (ferrocenyl, ferrocenylmethyl, and ferrocenylphenyl carbene) to 1,1 -diphenylethylene have been examined by means of the thermal decomposition of the corresponding acylferrocene tosylhydrazone sodium salts. Then, the reactivities of the ferrocenylcarbenes have been compared with those of the corresponding phenyl and <I>p</I>-anisylcarbenes. It has been found that, of the carbenes investigated, the ferrocenylcarbenes show the lowest reactivity in addition reactions to the olefin. It has been established by a study of the NMR spectra that, in the ferrocenylcyclopropanes only, there is a restricted rotation about the bond between ferrocenyl and cyclopropyl groups. On this basis, the reactivity of the ferrocenylcarbenes has been discussed in terms of the steric hindrance of the bulky ferrocenyl group.
