Cyclopropanoid cyanoesters of the formula: ##STR1## where R' is --CH.sub.3 or --CH.sub.2 CH.sub.3, and A is (a) --H, or (b) A, B represents an aliphatic group joined to a carbon atom on the cyclopropanoid ring, thereby forming a spiro group, A, B being selected from structures having the formula: (i) --(CH.sub.2).sub.n --, wherein n=3, 4, or 5, and (ii) --(CH.sub.2).sub.2 --Y--(CH.sub.2).sub.2 --, wherein Y is NCH.sub.3, O, or S); and, when A is --H, B is selected from the group consisting of: ##STR2## are disclosed. These compositions are useful in the synthesis of pyrethroids. A process for synthesis of cyclopropanoid cyanoesters by reacting 2-nitropropane with cyanoesters of the general formula: ##STR3## is also disclosed and claimed.
公开了式子为:##STR1##的环丙烷基氰酯,其中R'为--CH.sub.3或--CH.sub.2 CH.sub.3,而A为(a) --H,或者(b) A,B代表连接到环丙烷基环上碳原子的脂肪基,从而形成螺环,A,B选自具有以下公式的结构:(i) --(CH.sub.2).sub.n --,其中n=3、4或5,以及(ii) --(CH.sub.2).sub.2 --Y--(CH.sub.2).sub.2 --,其中Y为NCH.sub.3、O或S);当A为--H时,B选自以下组中的一种:##STR2##这些组合物在拟除虫菊酯的合成中有用。还公开了一种通过反应2-硝基丙烷和通式为:##STR3##的氰酯合成环丙烷基氰酯的方法。
