produced respectively upon treatment of 3,3-dichloropropene with lithium diisopropylamide alone or in the presence of potassium tert-butoxide, show opposite regioselectivity in the reactions with substituted benzaldehydes.
宝石-Dichloroallyl锂和宝石-dichloroallyl钾,用二异丙氨基锂单独使用或以钾的存在下分别产生处理后3,3-二氯丙烯的叔丁醇,显示与取代的苯甲醛的反应中区域选择性相反。
