Irradiation of benzil in acetonitrile in the presence of (E)- and (Z)-but-2-enyl-, pent-2-enyl-, and hex-2-enyl-tributylstannanes afforded the corresponding (E)- and (Z)-homcallylic alcohols, respectively, with complete retention of the original double bond configuration in good yields.
在(E)-和(Z)-丁-2-烯基、戊-2-烯基和己-2-烯基三
丁基锡烷存在下,在
乙腈中辐照苯偶姻,可分别得到相应的(E)-和(Z)-高烯丙基醇,并以良好的收率完全保留了原始双键构型。
