The allylation, crotylation and prenylation of aldehydes and ketones with stable and easily handled allylic carbonates is promoted by a Ti/Pd catalytic system. This Ti/Pd bimetallic system is especially convenient for the allylation of ketones, which are infrequent substrates in other related protocols, and can be carried out intramolecularly to yield five- and six-membered cyclic products with good stereoselectivities. In addition, Ti/Pd-mediated reductions and Wuertz-type dimerisation reactions can be readily carried out from allyl carbonates and carboxylates.

The reaction of allylic acetates with zinc in the presence of a catalytic amount of hexacarbonylmolybdenum(0) led to reductive coupling for the formation of a 1,5-diene framework.Reductive coupling of nerolidyl acetate provided squalene and its isomers in high yield.

Allylic p-tolyl sulfones were easily desulfonylated to the corresponding alkenes by LiHBEt3 in the presence of a catalytic amount of under mild conditions with the preservation of the original stereochemistry.This reaction was successfully applied to the synthesis of squalene.
Complexes η3-allylpalladium : isomerisation et photolyse ; synthese du squalene

Complexation of primary allylic chlorides in the presence of Pdo may lead to a mixture of syn and anti η3-allylpalladium complexes.Photolysis or thermolysis also causes syn-anti isomerisation.A mixture of squalene stereoisomers is obtained by photolysis of the η3-farnesylpalladium complexes.
