One-Pot Synthesis of Styrene Derivatives from Allyl Silanes via B(C 6 F 5 ) 3 -Catalyzed Isomerization-Hiyama Coupling.

Herein, we report a one-pot synthesis of styrene derivatives via a novel B(C 6 F 5 ) 3 -catalyzed E -selective isomerization of readily accessible allyl silanes and subsequent Hiyama coupling of the versatile alkenyl silane intermediates. This one-pot, two-step approach enables access to a broad range of styrene derivatives, including those containing Lewis basic functional groups, that cannot be accessed via the previously developed B(C 6 F 5 ) 3 -catalyzed isomerization of allyl benzenes.
