AN EFFICIENT SYNTHESIS OF α-(BENZOTHIAZOL-2-YLOXY)PHOSPHONATES DERIVATIVES

摘要

Fifteen title compounds 3a-0 were synthesized by condensationof 2chloro-benzothiazole with a-hydroxyphosphonates in good yields us-ing potassium iodide/tetrabutyl ammonium bromide as catalyst.All new com-pounds have been identified by ~1H-NMR,IR and elemental analysis.
