出　　处：《Chinese Chemical Letters》1995年第8期653-654,共2页中国化学快报（英文版）

摘　　要：The addition teaction of Grignard reagents to a-cinnamoyl ketene (1, 2-ethylene) dithioncetals 4 was examined.The results showed that the 1, 4-manner nucleoohilie attack at the cinnamoyl carbon double bond occurred. Possihle mechanism about the reaction selectivity is discussed.The addition teaction of Grignard reagents to a-cinnamoyl ketene (1, 2-ethylene) dithioncetals 4 was examined.The results showed that the 1, 4-manner nucleoohilie attack at the cinnamoyl carbon double bond occurred.
