for the preparation of 2‐mercaptobenzaldehyde, 2‐mercaptocyclohex‐1‐enecarboxaldehydes and 3‐mercaptoacrylaldehydes [(Z)‐3‐mercapto‐2‐methyl‐3‐phenylacrylaldehyde, 3‐mercapto‐3‐(o‐tolyl)acrylaldehyde)] starting from ortho‐bromobenzaldehyde, 2‐chlorocyclohex‐1‐enecarbaldehydes, (Z)‐3‐chloro‐2‐methyl‐3‐phenylacrylaldehyde and 3‐chloro‐3‐(o‐tolyl)acrylaldehyde is reported. The reaction of sulfur with the
一种新颖的一锅法制备2-巯基苯甲醛,2-巯基环己-1-烯醛和3-巯基丙烯醛[(Z)-3-巯基-2-甲基-3-苯基丙烯醛,3-巯基3-(o -[甲苯基)丙烯醛]]从邻-溴苯甲醛,2-氯环己基-1-烯醛,(Z)-3-氯-2-甲基-3-苯基丙烯醛和3-氯-3-(邻甲苯基)丙烯醛开始。硫与乙缩醛的格氏试剂用于保护醛基的反应通过用稀盐酸水解以高产率提供标题化合物。
