摘要：

(Chemical Equation Presented) ansa-[2]Borabis(benzene)chromophane and ansa-[2]boraferroarenophane were treated with alkynes in the presence of catalytic amounts of platinum or palladium/charcoal (see example) to afford the corresponding ansa-bis(boryl)alkenes in excellent yields and without detectable side products. The use of Pt and Pd are the first examples of diboration reactions of alkynes to be conducted under heterogeneous conditions. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
