Abstract

Abstract Benzimidazole-2-carbonitrile oxide was prepared in situ and reacted with vinyl acetate, acrylonitrile, styrene, phenyl vinyl sulfone and 3, 3, 3-trifluoropropene to afford 2-(5'- acetoxyisoxazolin-3'-yl)-, 2-[(5'-cyanoisoxazolin-3'-yl)-, 2-(5'-phenylisoxazolin-3'-yl)-, 2-[(5'- phenylsulfonyl) isoxazolin-3'-yl]-and 2-[(5'-(trifluoromethyl) isoxazolin-3'-yl)]-benzimidazole respectively. 2-(5'-Acetoxyisoxazolin-3'-yl) benzimidazole was converted into 2-(isoxazol- ...
