A range of palladacyclic and platinacyclic catalysts have been tested for activity in the allylation of aldehydes with allyl tributyltin. The bulky, pi-acidic palladacycle [Pd(mu-Cl)kappa(2)-P,C-P(OC6H2-2,4-Bu-t(2))-(OC6H3-2,4-Bu-t(2))(2)}}(2)] shows particularly good activity at room temperature with a variety of unsaturated substrates.
