The Heck reaction of aryl halides with simple alk-1-enes is a powerful method for the synthesis of (E)-1-arylalk-1-ene derivatives. The major problem of this reaction is the palladium-catalysed migration of the carbon-carbon double bond along the alkyl ch

Isolated pentacoordinate alkoxy-substituted alkenylsilicates, are readily prepared by mixing alkenyltrialkoxysilane, catechol and triethylamine at room temperature.Cross-coupling reactions of these alkenylsilicates with organic halides or triflates are catalyzed by a palladium complex and proceed very smoothly and cleanly to give the corresponding alkenes.The cross-coupling reactions could be also attained by a one pot operation without isolation of pentacoordinate organosilicates.The mechanism of this cross-coupling reaction is also described here. alkoxy-substituted alkenylsilicate / pentacoordinate silicate / cross-coupling / palladium catalyst / aryl halide / aryl triflate / styrene derivative / 1,3-diene
