Descripción

2-Ethyl-1,2-benzisoxazolium tetrafluoroborate (BEBT) is a bromonium ion that can be synthesized by reacting triethyloxonium chloride with chloroformate. It is an active site for the addition of amide groups. The formation of BEBT has been shown to be inhibited by acetonitrile and chloride ions, and it can be used as a filtration medium. This compound also has been shown to react with diphenyl sulfoxide and carbon tetrachloride to form a 2-ethoxycarbonylbenzisoxazole. The reaction of BEBT with piperidine and phosphorus oxychloride generates silver trifluoromethanesulfonate (AgOTf). Reaction of BEBT with triethyl orthoformate yields the desired product in preparative quantities.
