one-pot reactions of bromotrinitromethane with bicyclobutylidene and methylenecyclobutanes provide a simple route to halogen-substituted isoxazolidines of mixed composition. With these same olefins, iodotrinitromethane gives adducts which decomposed rapidly to yield the corresponding isoxazolines. Reaction of bromotrinitromethane and bicyclobutylidene with electron-deficient alkenes produced isoxazolidines

Three-component one-pot reactions of tetranitro- and bromotrinitromethanes with alkoxyacetylenes, mediated by diazomethane or bicyclobutylidene, yielding gem-dinitroaziridines via sequential electrophile transfer followed by [3+2]-cycloaddition, have been studied. A series of novel N-alkoxy-2,2-dinitroaziridines have been prepared by these reactions.
