NERYLTRIETHYLAMMONIUM AND GERANYLTRIETHYLAMMONIUM HALIDES IN THE ALLYLATION OF SODIUM DIETHYL MALONATE - THE EFFECT OF THE LEAVING GROUP OFTHE ALLYLATING REAGENT ON THE SELECTIVITY OF THE REACTION

In the absence of catalysts, N-neryl- and N-geranyltriethylammonium ha lides can allylate sodium diethyl malonate to give terpene malonate de rivatives. Using the above-mentioned ammonium salts, geranyl and neryl acetates, geranyl ethyl carbonate, and geranyl diethyl phosphate as e xamples, it has been shown that with Pd-0 and Pd-II catalysts, the sel ectivity of the formation of neryl-, geranyl-, and linalylmalonates ca n be governed by varying the leaving group of the allylating agent.
