A new synthesis of mono-and dialkynylisothiazoles by cross-coupling of bromine-and iodine-containing isothiazoles with terminal acetylene moieties in the PdCl2(PPh3)(2)-CuI-NEt3 catalytic system has been developed.
Synthesis of bromine-and iodine-containing perhaloisothiazoles
摘要:
A method was developed for the synthesis of bromine- and iodine-containing perhaloisothiazales by bromination and iodination of 3-bromoisothiazole prepared from the available 3-hydroxyisothiazole.
