Reaction of bis (π-allyl)dipalladium dichloride with diethylcadmium and bis (triethylgermyl) cadmium

1. The reaction of bis (π-allyl)dipalladium dichloride with diethylcadmium, bis(triethylgermyl)cadinium, and bis (triethylgermyl)mercury was studied. The reaction proceeds with the initial formation of the 1∶1 adduct and subsequent exchange reaction. 2. The decomposition of the intermediate [AllPdR] compounds depends on the nature of the E group. When R=Et the decomposition proceeds via the intermediate formation of the π-olefin complex and the subsequent liberation of ethylene. When R=Et3Ge the decomposition includes the disproportionation reaction and the radical decomposition of the disproportionation products.
