Dehydrohalogenation of adducts of dichlorocarbene with cyclooctene and its peripherally cyclopropanated analogs
摘要:
Dehydrohalogenation of three isomeric adducts of dichlorocarbene with bicyclo[6.1.0]non-1-, -2-, and -4-enes under the action of potassium tert-butoxide in DMSO was studied. In the course of dehydrohalogenation of the substrates under study, different isomerization processes, which were accompanied by repeated migrations of multiple bonds that formed, occurred depending on the structure of dichlorides, while no skeletal rearrangements were observed.

An improved method for the generation of dichlorocarbene was developed that utilizes ultrasound in the reaction of carbon tetrachloride with magnesium. High yields of gem-dichlorocyclopropane derivatives can be obtained in the presence of olefins by this method.
