Synthesis of perhydro-1,4-selenazines and perhydro-1,4-tellurazines containing a sulfamide group
Dehalogenation products were obtained under conditions for the two-phase selenohalogenation of N,N-diallylarylsulfamides in addition to the major products, 1,1-dihalo-2,6-dihalomethyl-4-arylsulfonylperhydro-1,4-selenazines. Phenylselenium trihalides form derivatives of perhydro-1,4-azaselenonium halides. Tellurohalogenation gives analogous results but tetrabromotellurium partially forms intermolecular complexes.
