REGIOCHEMISTRY AND STEREOCHEMISTRY OF OXIRANE RING-OPENING WITH SILYL HALIDES

Detty, Michael R.,Seidler, Mark D.

, p. 2543 - 2546 (2007/10/02)

The ring-opening of various styrene and stilbene oxides with silyl halides was examined.The regiochemistry of ring-opening was independent of the silyl halide used, but the stereochemistry of ring-opening was sensitive to both the choice of halide and the steric bulk of groups attached to silicon.
