Novel 2H-1,3-benzoxazine ring formation by intramolecular heterocyclization of N-(α-aryloxyalkyl)imidoyl chlorides
A convenient synthetic approach to derivatives of 2-trichloromethyl and 2-dichlorometylene-2H-1,3-benzoxazines, based on intramolecular heterocyclization of readily accessible N-(α-aryloxytrichloroethyl)imidoyl chlorides, was developed. Base induced dehyd

Synthesis of α-(acylamino)polyhaloalkylphosphoryl compounds by the reaction of trivalent phosphorus chlorides with N-(α-hydroxypolyhaloalkyl)amides
N-(α-Hydroxypolyhaloalkyl)amides react with trivalent phosphorus chlorides to give α-(acylamino)polyhaloalkylphosphoryl compounds via phosphorotropic rearrangement of intermediate phosphites or phosphinites.
