Article abstract of DOI:10.1055/s-1992-26146

The synthesis of novel N-sulphonyl-1H-azepines is described starting from arylsulphonyl chlorides in a one-pot operation making use of solid-liquid phase-transfer catalysis technique (benzene/sodium bicarbonate). Good yields were obtained under moderate reaction conditions.
