Abstract
Abstract The homolytic arylation (substituents in the phenyl radical: none, p-methyl, p-fluoro, p-chloro, p-bromo, o-chloro, 2, 4-dichloro, 3, 5-dichloro, 2, 3, 4-trichloro, 2, 3, 5-trichloro, o- carbomethoxy, p-carboethoxy, and o-phenyl) and heteroarylation (2-thiazolyl, 2- benzothiazolyl, 3-pyridyl) of coumarin and benzo [b] furan has been studied. The radicals were generated by thermal decomposition of the corresponding 1, 3-diaryltriazenes in the ...
