各种烯基锆化合物的合成及其在立体选择性合成二(三)取代的烯烃中的应用

Synthesis of Various Vinylzirconium Compounds and Their Application in Stereoselective Synthesis of Di-and Tri-substituted Alkenes

烯基锆化合物及硒基烯基锆化合物、锡基烯基锆化合物、磺酰基烯基锆化合物、亚磺酰基烯基锆化合物、硅基烯基锆化合物等金属或杂原子取代的烯基锆化合物 ,可通过锆氢化反应高产率和高选择性地制得 .

Disubstituted and trisubstituted alkenes were prepared stereoselectively via the reaction of vinylzirconium, selanylvinylzirconium, stannylvinylzirconium, vinylzirconium sulfone, vinylzirconium sulfoxide and silylvinylzirconium compounds, which were achieved in high yields and high stereoselectivity via hydrozirconation of the corresponding compounds with various electrophilic reagents.
