The BF3-catalyzed decomposition of diazo carbonyl compounds in nitriles have afforded the corresponding oxazoles in high yields. This method is applicable to diazo carbonyl compounds such as m- and p-substituted diazoacetophenones, ethyl diazoacetate, 1,2-diphenyl-2-diazoethanone, dibenzoyldiazomethane, and dimethyl diazomalonate. Bis(diazo ketone)s such as terminal bis(diazoacetylated) alkanes (III1−4:
