1,3-Dithianes 1, 1,3-dithiolanes 2, and diphenyl dithioacetals 3 derived from cinnamaldehydes reacted with 2,3-dichloro-5,6-dicyano-p-benzoquinone in aqueous solvents to give benzaldehydes 4. Hydride transfer from 1–3 to 2,3-dichloro-5,6-dicyano-p-benzoquinone followed by hydrolysis and oxidative carbon-carbon bond cleavage would produce benzaldehydes 4.
1,3-二噻烷1,1,3-二硫戊环2,和二苯基二硫3从肉桂醛衍生与2,3-二氯-5,6-二氰基反应p苯醌在水性溶剂中,得到的苯甲醛4。氢化物从1-3转移到2,3-二氯-5,6-二氰基对苯醌,然后水解和氧化碳-碳键裂解会生成苯甲醛4。
