A new palladium-catalysed synthesis of 1,1-dialkylbuta-1,3-dienes via organoboron intermediatesDedicated to Professor Iacopo Degani on the occasion of his 70th birthday.
Abstract
Iodobenzene and tetrakis(triphenylphosphine)palladium(0) [(C6H5)3P]4Pd catalyse a new synthesis of 1,1-dialkylbuta-1,3-dienes, starting from 1,1-diethoxybut-2-ene and trialkylboranes, in the presence of Schlosser’s superbase LIC–KOR.
