摘要：

Carbofuran (2,3-dihydro-2,2 dimethyl benzofuranyl-7-yl-methyl carbamate, I) when irradiated by sunlight in different solvents furnished several photoproducts. Eleven compounds have been characterized, out of which nine compounds (II to X) by GC/MS and two compounds (XI and XII) by direct comparison with authentic samples. Another two compounds were isolated in pure form and identified by MS and NMR analysis. The main degradation pathways involved hydrolysis, oxidation, methylation, chlorination and rearrangement. The plausible pathway of photodegradation of carbofuran has been depicted. © 1990.
