Abstract
The treatment of pinacolborane (4,4,5,5-tetramethyl-1,3,2-dioxaborolane) with vinylarenes in the presence of a catalytic amount of phosphine-free di-μ-chlorobis(1,5-cyclooctadiene)dirhodium(I) [RhCl(cod)]2, through dehydrogenative borylation, provides the corresponding regio- and stereodefined (E)-2-arylethenylboronates in high yields. Also, a ruthenium complex prepared in situ from (1,5-cyclooctadiene)(1,3,5-cyclooctatriene)ruthenium(0) [Ru(cod)(cot)] and P(4-CF3C6H4)3 showed considerable catalytic activity for dehydrogenative borylation.
