Abstract

1,145,187. Quaternary heterocyclic compounds. AGFA-GEVAERT A.G. 28 Dec., 1966 [28 Dec., 1965], No. 57878/66. Heading C2C. [Also in Division G2] 6 - Azonia - 9 - thia - spiro - 5,5 - undecane bromide is prepared by reacting thiomorpholine and 1,5 - dibromopentane. 6 - azonia - 3,9- thia - spiro - 5,5 - undecane chloride - 9 - dioxide is prepared by reacting thiomorpholine hydrochloride with divinyl sulphone. Used as chemical sensitizers in photography (see Division G2).
