Imikhiqizo

I-complex [Cp*Ru(MeCN)3]PF6 ikhonjiswa ukwenza i-hydrosilylation yohlu olubanzi lwama-alkynes.Ama-alkynes asetheminali akwazi ukufinyelela emikhiqizweni ye-alpha-vinylsilane ene-regioselectivity enhle.Ucwaningo lokulebula lwe-Deuterium lubonisa ukuthi inqubo yokwengeza ehlanzekile iyasebenza.Inkimbinkimbi efanayo iyasebenza ku-alkyne hydrosilylation yangaphakathi, lapho ukukhetha okuphelele kwenqubo yokwengezwa kwe-trans kugcinwa.Amakilasi amaningana e-alkyne substrate yangaphakathi, okuhlanganisa i-propargylic alcohols ne-alpha,beta-alkynyl carbonyl compounds, avumela ukwakheka kwe-regioselective vinylsilane.Ukubekezelelwa kwezinhlobonhlobo ze-silane kuyaphawuleka, kufaka phakathi i-alkyl-, aryl-, alkoxy-, kanye ne-halosilanes.Le nzuzo iboniswa ekuhlanganiseni okuqondile kwama-triene substrates we-silicon-tethered intramolecular Diels-Alder cycloadditions.
