Syntheses of new lithio hexavinylogation reagents are described starting either from ω-bromo polyenacetal, ω-bromo polyenol ether or ω-bromo non conjugated aldehyde. The reactivity of the lithio reagents has been tested by condensation with benzaldehyde; the resulting hexaenal has been obtained in a one or two steps procedure.
从ω-

硫代六
乙烯基缩合试剂的合成。
硫代试剂的反应性已通过与
苯甲醛缩合的方法进行了测试;所得到的
己醛已通过一两步程序获得。
