Novel 2-vinyl(or ethyl)-1-cyanocyclopropane-1-carboxylates and 2-vinyl(or ethyl)-1-arylcyclopropane-1-carboxylates useful as herbicides, pesticides and chemical intermediates are provided. The invention also relates to a method of modifying plant growth by the application of vinyl(or ethyl)cyclopropane derivatives wherein the carboxylate group contains an amine or quaternized amine moiety.

copper-catalyzed three-component carboamination of atropates for the synthesis of α-aryl amino acid derivatives is presented. The scope of the reaction is explored with respect to all three coupling partners: the alkyl halide, the atropate, and the aryl amine. A total of 41 examples are included, with yields of ≤92%. Both primary and secondary aryl amines participate in the carboamination along with α-haloesters

This invention provides a convenient and commercially adaptable process for the preparation of vinylcyclopropane derivatives in high yieid. For the process an alkylating agent and activated methylene compound are reacted in the presence of an alkylene oxide derivative and alkali metal compound. Water can also be present and/or the reaction may be carried out in an inert organic diiuent.
