a malodorous procedure as an odorless reagent that was usable in place of 1,3-propanedithiol (1) in organic reactions, e.g., in the reduction of azides and protection of carbonyl groups. The 1,3-dithioacetals obtained in the latter reaction were effectively reduced to methylene with Raney nickel and reconverted to the original carbonyl compounds by hydrolysis with N-bromosuccinimide in aqueous 2-butanone
制备2-十二烷基-1,3-丙二酚(2a)时无需进行任何恶臭操作即可作为无味试剂,可在有机反应中代替1,3-丙二酚(1),例如用于减少叠氮化物和保护羰基。在后一反应中获得的1,3-二硫缩醛与阮内镍有效地还原为亚甲基,并通过在2-丁酮水溶液中用N-溴代琥珀酰亚胺水解而转化为原始的羰基化合物。另外,由2a制得的1,3-二硫杂环己烷和甲醛的阴离子可以用作阴离子羰基碳的合成等价物。
