Abstract
The photocatalysis synthesis of 2-methylquinoxaline 1,4-dioxide (2MQOX) was investigated by the cycloaddition reaction of Benzofurazan oxide with acetone at 254 nm with yield 65% and the quantum yield was calculated (0.03).The structure of the resultant was elucidated by spectroscopic analysis (IR, UV, and 1 H, 13 C NMR). A mechanism for the reaction was proposed using the density functional theory (DFT / B3LYP (6-311 + G (2d)). The molar ratio of reaction was 1: 1 . Keywords: quinoxaline , density functional theory , mechanism, spectroscopic analysis .
