Abstract
A process for the addition of compounds containing silicon-bonded hydrogen to compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by visible radiation and is conducted in the presence of a platinum complex having one cyclopentadienyl group that is eta-bonded to the platinum atom and three aliphatic groups that are sigma-bonded to the platinum atom and a sensitizer that is capable of absorbing visible light and is capable of transferring energy to said platinum complex such that the hydrosilation reaction is initiated upon exposure to visible light. The invention also provides for use in the aforementioned process.
