摘要：

One of the photodegradation processes in toluene solution of indolinospironaphthoxazine compounds can be explained by the reaction of ambient oxygen with the biradical species involved during the ring opening of the closed form of the photochromic compound. This reaction leads to N-dealkylation of the N-alkyl substituted indoline moiety giving 3,3-dimethyloxindole. The direct UV irradiation of 1,3,3-trimethyloxindole giving no 3,3-dimethyloxindole, the N-dealkylation process takes place from the initial photochromic structure.
