Abstract
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 dith iones 9a,b. N-Methyl barbituric acid (10b) reacted with LR to produce the e nethiole 11 and the sulfide 12. Pyrazolone derivatives 13 and 17 reacted wi th LR in different molar ratios to form the corresponding products 15, 16 a nd 19. Rohdanine (20) reacted with LR to give the enethiole 22 and the disu lfide 23.
