Synthesis and properties of vinyl derivatives of 4,5-diphenyl-2-mercaptoimidazole

S-Vinyl-, N,S-divinyl-, and S-ethyl-N-vinyl-4,5-diphenyl-2-mercaptoimidazoles were synthesized by reaction of 4,5-diphenyl-2-mercaptoimidazole with acetylene under pressure. The reactivities of these monomers were investigated. It is shown that they have lower reactivities than S-and N,S-vinyl-2-mercaptobenzimidazoles in radical polimerization reactions and do not form complexes with transition metal salts.
