The vinylation of arenes using 1-(phenylthio)vinylstannanes proceeded in the presence of tin(IV) chloride and molecular sieves 4A to afford 1-arylalkenyl sulfides in good yields. The stereochemistry of the olefinic moiety was determined after oxidation to the corresponding sulfones and it was found that the present reaction gave the thermodynamically stable stereoisomers.
在氯化锡(IV)和分子筛4A的存在下,使用1-(苯硫基)乙烯基锡烷对芳烃进行乙烯基化,以高收率得到1-芳基链烯基硫化物。氧化成相应的砜后,确定烯烃部分的立体化学,发现该反应给出了热力学稳定的立体异构体。
