Platinum-catalyzed elimination-addition reactions of trisilylethenes

(E)-1-Hexyldimethylsilyl-1,2-bis(trimethylsilyl)ethene (1) and (E)-1-(3'-butyl-1',3'-tetramethyldisiloxanyl)-1,2-bis(trimethylsilyl)ethene (7) undergo isomerization-redistribution reactions catalyzed by platinum.Each of them is converted into its (Z)-isomer and ethenes bearing one trimethylsilyl group and two substituted silyl groups as major products.The proposed mechanism for the reactions involves a sequence of eliminations of hydrosilanes from the ethenes and re-addition to them.Oxygen greatly affects the reaction apparently accelerating anti-elimination of hydrosilanes.
New aspects of platinum-catalyzed hydrosilylation of disilylethynes
Suzuki, Toshio,Lo, Peter Y.
, p. 19 - 25 (2007/10/02)
The platinum-catalyzed hydrosilylations of bis(trimethylsilyl)ethyne and 1-trimethylsilylethynyl-1,1,3,3,5,5,7,7,7-nonamethyltetrasiloxane at 130-150 deg C were investigated using high molecular weight organosilicon hydrides.In addition to the expected adducts, significant amount of unexpected disilylethynes and trisilylethenes were produced.It is suggested that the reaction sequence involves elimination of silanes from the primary adducts to form disilylethynes and subsequent addition reactions to form various trisilylethenes.
