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
