Mild and General Cross-Coupling of (α-Alkoxyvinyl)silanols and -silyl Hydrides
摘要:
[GRAPHICS](alpha-Alkoxyvinyl)silanols and (alpha-alkoxyvinyl)silyl hydrides are efficiently converted to aryl vinyl ethers by a palladium(0)-catalyzed cross-coupling reaction with aryl halides in the presence of tetrabutylammonium fluoride or hydroxide. Yields are generally high, and the reaction is compatible with a wide range of functional groups.
