(E)-2-Butyldimethylsilyl-1-trimethylsilylhex-1-ene 1 and (E)-1-butyldimethylsilyl-2-trimethylsilylhex-1-ene 4 undergo platinum-catalysed isomerisation reactions with migrations of carbon-carbon double bonds to form (E)- and (Z)-1,2-disilylhex-2-enes at elevated temperatures. The reactions proceed under nitrogen but not under dry air. The structures of the products were determined using H-1, Si-29, two-dimensional H-1-Si-29, and selectively decoupled Si-29 NMR techniques.
