Crystal Structure of 1,1-Dimethylethyl N-(2-Oxo-2H-1-benzopyran-3-yl)carbamate

Abstract

t-Butyl coumarin-3-carbamate (1), which was prepared by the reaction of t-butanol with coumarin-3-carbonyl azide, has herbicidal activities. The crystal structure of 1 was analyzed by single-crystal X-ray diffraction. The carbamate group makes an angle of 8.16(5)° with the coumarin ring. Intermolecular C-H…O interactions were observed in the crystal structure.
