In the reaction of vinyloxybenzenediazonium ion with aromatic amines conditions were found for the C-coupling reaction in an aqueous methanol medium, and a series of new amino- and dialkylamino-substituted vinyl ethers of azobenzenes were synthesized.Treatment of solutions of vinyloxybenzenediazonium chloride with copper chlorides or cyanides leads to the addition of Cl- or CN- in the aromatic ring with the elimination of nitrogen, and the reaction of vinyloxybenzenediazonium ion with the chloride ion is complicated by side processes in the vinyloxy group.A method is developed for the synthesis of m- and p-vinyloxycyanobenzenes.
