摘要:
Compounds consisting of a variously substituted unsaturated aliphatic chain and a terminal vinyl dichloro or trichloro substituted residue are disclosed, as well as a process for preparing them. The compounds are insecticides which exhibit an activity similar to that of the juvenile hormone and inhibit the development and metamorphosis of various insects.
