STUDIES ON ORGANOPHOSPHORUS COMPOUNDS V1-4. REACTION OF 2,4-BIS(4-METHOXYPHENYL)-1,3,2,4-DITHIA DIPHOSPHETANE-2,4-DISULFIDE WITH CYCLIC AND HETEROCYCLIC KETONES
摘要:
Cyclic ketones 2 and 8a,b reacted with Lawesson's reagent (1) in different molar ratios to give the oxathiaphosphole (4), the disulfide 7 and the dithiones 9a,b. N-Methyl barbituric acid (10b) reacted with LR to produce the enethiole 11 and the sulfide 12. Pyrazolone derivatives 13 and 17 reacted with LR in different molar ratios to form the corresponding products 15, 16 and 19. Rohdanine (20) reacted with LR to give the enethiole 22 and the disulfide 23.
