The reaction of N,N-diethylamino-tributyltin with aryl bromides in the presence of a catalytic amount of PdCl2(o-tolyl3P)2 gave N,N-diethylaminobenzene derivatives. The reaction is a new kind of amination different from ones through aryne or SRN1 mechanise

Reaction of ethyl α-(tributylstannyl)acetate with aryl bromides in the presence of zinc bromide or chloride and a catalytic amount of dichlorobis(tri-o-tolylphosphine)palladium was found to give ethyl arylacetates in good yields except with the aryl bromide having p-acetyl or p-nitro group.
