Abstract The acetolyses of hexaaryldileads (XC6H4)6Pb2 in which X is H, p-CH3O, m- and p-CH3, m- and p-Cl and 2,5-(CH3)2, have been examined kinetically at 40° in 1 3 acetic acid/dioxane solution. Hexaphenyldilead has been examined also at several temperatures, in two other acetic acid/dioxane solutions and in the presence of various added salts and tetraphenyllead. The results are not consistent with a prior dissociation to tetraaryllead and diaryllead, but correspond to electrophilic CPb cleavage to yield a partially acetoxylated derivative which decomposes to the observed products triaryllead acetate, diaryllead diacetate, lead(II) acetate and aromatic hydrocarbon. Partially acetoxylated derivatives, Ar3Pb2(OCOCH3)3 where Ar is phenyl and p-tolyl, have been prepared in acetic anhydride/acetic acid solution and on the basis of mass spectra are suggested to possess the unsymmetrical (CH3COO)Ar2PbPbAr(OCOCH3)2 structures. Employing 14C labelled materials it has been found that no detectable exchange takes place between hexaphenyldilead and tetraphenyllead in benzene or tetrahydrofuran solution at 40°, nor between hexaphenyldilead and triphenyllead chloride in benzene solution at 40°.
