The reactions of 1, 2-epoxypropane (I) and 2-methyl-2, 3-epoxypentane (II) with various primary and secondary amines and with hexahydrophthalic anhydride in the presence of hydroxylic catalysts have been studied. The direction of ring opening of the epoxides on reaction with the amines is unaltered by the presence of phenol as catalyst, and involves attack at the least substituted carbon atom of the epoxide ring. The structures of the ...
