Cov khoom

Lub complex [Cp*Ru(MeCN)3]PF6 yog qhia los catalyze hydrosilylation ntawm ntau yam alkynes.Terminal alkynes muaj peev xwm nkag mus rau alpha-vinylsilane cov khoom nrog zoo regioselectivity.Deuterium labeling cov kev tshawb fawb qhia tau hais tias cov txheej txheem huv trans ntxiv yog ua haujlwm.Tib txoj kev ua haujlwm nyob rau hauv alkyne hydrosilylation, qhov kev xaiv zoo rau cov txheej txheem sib txuas ntxiv yog khaws cia.Ntau chav kawm sab hauv alkyne substrate, suav nrog cov cawv propargylic thiab alpha, beta-alkynyl carbonyl compounds, tso cai rau kev tsim cov vinylsilane regioselective.Kev ua siab ntev ntawm ntau yam ntawm silanes yog qhov tsim nyog, suav nrog alkyl-, aryl-, alkoxy-, thiab halosilanes.Qhov kom zoo dua no tau pom nyob rau hauv qhov ncaj qha synthesis ntawm triene substrates rau silicon-tethered intramolecular Diels-Alder cycloadditions.
