Kinetic study of reactions of carbodiimides with α-oxides, and structure of the resulting compounds☆

Abstract The influence of various factors affecting features of reactions of carbodiimides with α-oxides has been investigated. The main product of the interaction of diphenyl carbodiimide with phenylglycidyl ether is 3-phenyl-5-phenoxymethyl-2N-phenyliminooxazolidine; the formation of diphenylcarbodiimide dimer and 3-phenyl-5-phenoxymethyl-2-oxazolidone is also possible. When oligomeric initial products are used the resulting unit-type heterogeneous polymers contain iminooxazolidine, oxazolidone and other chain fragments. The chain structure may be modified by altering the reaction conditions.
