Hi student..
Hydrosilylation reactions or catalytic hydrosilation are a widely used method to prepare organosilicon products. The reaction consists of the addition of Si-H bonds on unsaturated bonds like alkenes, alkynes or ketones, where catalysts are often required usually H2PtCl6. In other words it describes the addition of Si-H bonds across unsaturated bonds.
Alkenes and alkynes give alkyl and vinyl silanes; aldehydes and ketones give silyl ethers.An idealized transformation is illustrated by the addition of triethylsilane to diphenylacetylene:
Et3SiH + PhC&≡;CPh → Et3SiPhC=CHPh
