New benchrotrene derivatives have been prepared by reactions of [Cr(CO)s], etc., with oestrone and related steroids, phenalene, 2,6,15,19-tetrathia-[7.7]paracyclophane, PhjAs, and diphenic acid and related compounds. Ring-substituted derivatives of [( benzaldehyde)Cr(CO)3] have been resolved into enantiomeric forms. Reactions of carbene complexes of the type [(OQs-CrC(OMe)Ar] with alkynes have afforded derivatives of [(jy -naphthalene)-Cr(CO>3] (see Vol. 8, refs. 393, 394).
