Abstract
The cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)-cyclopentan e/[PdCl(C3H5)]2 system catalyses allylic amination in good yields with a very high substrate/catalyst ratio; a turnover number of 680 000 and a turnover frequency of 8125 h−1 can be obtained for the addition of dipropylamine to allyl acetate in the presence of this catalyst.
