WebMay 24, 2024 · The acyl halides are normally not soluble in water so the reaction is slow. Then, when the reaction proceeds, acid is formed and the pH decreases, reducing the reactivity of water. Ammonia and amines are much more nucleophilic and react much faster with the acyl halide. This reaction is so much faster that it can be carried out in water. WebApr 12, 2024 · The tyrosine monomer phenol oxygen radicals, monomer benzene carbon radicals, dimer phenol oxygen radicals, dimer benzene carbon radical are polymerized among them.
