Abstract
The addition reaction of triorganosilanes to 1-(5-methylhexene-5-yn-2-yloxy)-2,3-epoxypropane in the presence of H2PtCl6.6H2O catalyst proceeds via a triple bond, but with an advantageous yield (75-85%) of the β-isomer (relative to the oxygen atom). The addition of dimethylamine to the epoxy ring leads to secondary amino alcohols, and the corresponding episulfide is obtained by the reaction of epoxysilane with thiocarbamide. Epoxy-1,4-dienes can be used as modifiers for phenol-formaldehyde resin

The study has shown that the hydrosilylation of the indicated epoxyenin proceeds via a triple bond, but with the formation of βand γ-isomers, with a predominance of β-product (Figure 1) [3]
Summary
Silanes having the Si–H bond are extremely easy to attach to various unsaturated hydrocarbons and other organic and organic elemental compounds with double and triple bonds [1]. Even though the hydrosilylation method has been used for about 60 years, interest in it has not waned to this day. This was previously caused by its universality since a silyl group with the desired function can be attached to almost any unsaturated compound. The study has shown that the hydrosilylation of the indicated epoxyenin proceeds via a triple bond, but with the formation of βand γ-isomers (relative to the oxygen atom), with a predominance of β-product (Figure 1) [3]
