Several methyl(allyl)thallium derivatives have been prepared for the first time. The IR and PMR spectra of these compounds indicate the presence of σ-allylthallium bonds. In the cleavage reactions of these compounds with tetramethyltin in methanol or with metal salts such as Hg(OCOCH3)2, PdX2 (X  OCOC2H5 and Cl) and RhCl3·3H2O, preferential cleavage of the allylthallium bond occurs to give propylene in the case of tetramethyltin and allylic derivatives of the metals in the other cases.
