Abstract
Cationic (η3-allyl) complexes of general formula [(η3-allyl)M(ligand)2]+Y−, where Y− is a non-coordinating anion (BF4−, ClO4−, BF4−) have been examined in telomerization reactions of buta-1,3-diene with representative nucleophiles. No reaction are observed for nickel complexes, due to their high reactivity versus nucleophiles. With palladium complexes, the reaction only occurs with alcohols and provides an increased selectivity for telomers with more than two diene units, leading to C16, C24 and even higher ethers. Although much less reactive, platinum complexes can also produce higher telomers when hydrogenosilanes are used. It is proposed, at least in the case of palladium, that the formation of C16 and C24 ethers arises from the coupling of C8 units within dimeric palladium intermediates with the telogen acting as a bridging ligand.
