A compound of the formula: ##STR1## wherein Y represents OH or a halogeno group; D represents hydrogen or a cyano group; B represents hydrogen or a methyl, ethyl or vinyl group; A represents methyl; n is 0, 1 or 2; with the proviso that (1) when the CH.sub.2 CH.dbd.CHB group is in the 4-position with respect to the CHDY group, then D must be hydrogen and B must be methyl, ethyl or vinyl and the configuration about the double bond in the CH.dbd.CHB group must be Z and (2) when the group CH.dbd.CHB is in the 3-position with respect to the CHDY group and D is CN then n must be 0 and (3) when the group CH.sub.2 CH.dbd.CHB is in the 2 or 3-position with respect to the CHDY group, then D is CN, are useful in the production of pesticidal esters of chrysanthemic and related acids.
该化合物的公式为:##STR1## 其中Y代表OH或卤素基团;D代表氢或氰基;B代表氢或甲基、乙基或乙烯基;A代表甲基;n为0、1或2;但需注意,(1)当CH.sub.2 CH.dbd.CHB基团相对于CHDY基团处于4位时,D必须是氢,B必须是甲基、乙基或乙烯基,且CH.dbd.CHB基团中的双键构型必须是Z;(2)当CH.dbd.CHB基团相对于CHDY基团处于3位时且D为CN,则n必须为0;(3)当CH.sub.2 CH.dbd.CHB基团相对于CHDY基团处于2或3位时,则D为CN。这些化合物在生产除草酸和相关酸的杀虫酯中非常有用。
