T. Yokozawa et al., LEWIS ACID-CATALYZED COUPLING REACTIONS OF ALLYL TRIMETHYLSILYL ETHERS WITH ALLYLSILANES, Tetrahedron letters, 36(29), 1995, pp. 5243-5246
For the simultaneous preparation of molecules having both the nucleoph
ilic and electrophilic sites, allyl trimethylsilyl ethers as electroph
ilic allylating reagents are studied. Allyl trimethylsilyl ethers reac
t with allyl trimethylsilanes in the presence of a catalytic amount of
ZnCl2 at room temperature to afford the corresponding 1,5-dienes in g
ood yields.
