gradually and a yellow solid began to appear after lh; the reaction was complete after 10 h (TLC). The crude product was purified by silicagel column chromatography to afford pale yellow crystals of 2-morpholinothioformy1-2-phenyl-4morpholino-5-phenyl1,3-dithiole (3a). Similarly, the reaction of compounds 2b-f and trimethyl phosphite gave analogous products 3b-f. Their structures were determined by IR
