3,5-Dinitrobenzoyl chloride (1) adds oxidatively to triarylantimony to give the first benzoyl derivatives of antimony, ArSbCl.Triphenyl-phosphine and -arsine, and also bis(p-methoxyphenyl)tellurium(II) react with 1 in the same way.Conductivity and molecular weight data show that the benzoyl derivatives exist in solution as monomeric species.The metal-acyl bond in the compounds is stable towards MeOH, MeI, and CdX2.Reaction of 1 with triphenylbismuth leads to the cleavage of one Bi-Ph bond.Attempts to prepare the benzoyl derivative, Ph3PbCOC6H3(NO2)2, by the reaction of 1 with hexaphenyldilead were unsuccessful, but one Pb-Ph bond was cleaved of Ph4Pb in the presence of 1.
