摘要：
The reaction of benzyne with several kinds of dithiolactones, such as beta-dithiolactone (9), benzothiophene-1-thione (13), 1,2-dithiolane-3-thione (20), and 3,3,5,5-tetramethyl-4-thioxothiolane-2-thione (7), afforded benzo-1,3-dithioles in moderate to good yields, whereas the reaction of benzyne with gamma-thionolactone (16) gave gamma-lactone and diphenyl disulfide.
