Tandem photoarylation-photoisomerization of halothiazoles: Synthesis, photophysical and singlet oxygen activation properties of ethyl 2-arylthiazole-5-carboxylates
The photochemical reaction between ethyl 2-chlorothiazole5-carboxylate and benzene gave no product. In contrast, the reaction with ethyl 2-iodothiazole-5-carboxylate gave ethyl 3-phenylisothiazole-4-carboxylate. The same behaviour was observed if the reac
