Hydrosilylation of allyl derivatives with T, D and M type hydrosilanes

• We report hydrosilylation of allyl derivatives with T, D and M type hydrosilanes.
• AA with T8H8 was found to be suitable for the Karstedt's catalyst/PPh3 systems.
• The formation of β-adduct could be suppressed by adding PPh3 to Karstedt's catalyst.
• The formal Tsuji–Trost reaction was observed in AA and AEE, but not observed in DMAA.

Hydrosilylation reactions of allyl derivatives (i.e., allyl acetate, N,N-dimethylallylamine and allyl ethyl ether) with hydrosilanes (i.e., octahydridosilsesquioxane, 2,4,6,8-tetramethylcyclotetrasiloxane, and tetramethyldisiloxane) were carried out in the presence of the Karstedt's catalyst in order to compare their structure–reactivity relationship. The effects of a phosphine ligand on the conversion and the selectivity were also investigated with PPh3 as an additive to the Karstedt's catalyst.

In this paper, we report hydrosilylation reaction of allyl derivatives with hydrosilanes consisting of T, D and M type skeletons by using Pt(dvs)/PPh3 catalyst system, in order to clarify whether there is any difference in reactivity depending on the structures of allyl derivatives as well as hydrosilanes.Figure optionsDownload as PowerPoint slide
