An appropriate selection of the [Pd/base/QX] catalyst systems allows one to direct at will the palladium-catalysed arylation of allyltrimethylsilane towards the formation of either (E)-1-aryl-3-(trimethylsilyl)-1-propene or 3-aryl-1-propene, by preventing or promoting efficiently the desilylation and the double bond migration.

Allylsilane and various vinyl substrates undergo selective C-H bond functionalization based boronation reactions using iridium catalysis. The products were further reacted with aryl and vinyl halogenides in a one-pot sequence. This method is suitable for regio- and stereoselective synthesis of various allylsilanes and dienylsilanes.
