The metallation of N,N-dimethylaminotoluene by palladium acetate. Evidence for a trinuclear species

Abstract

The reaction of cis or trans di(@m-chloro)bis{[2-(dimethylamino)phenyl]methyl}dipalladium with silver acetate affords the corresponding trans dimeric compound with two acetato bridges between the palladium atoms. The molecule is non-rigid in solution. A closer investigation of the product obtained previously from the reaction of the toluidine ligand (dmatH) with palladium acetate in acetic acid, shows that it is a trinuclear species of general formula Pd{3}(dmat){2}(@m{2}-O{2}CCH{3}){4}, similar to species observed in palladation of olefins by palladium acetate.
