ene, respectively, in the presence of several 1,3-dienes. Reactions of phenylphosphinothioylidene with 2,3-dimethylbutadiene and 1,3-cyclohexadiene gave Diels-Alder type reaction products, that is, 3,6-dihydro-1,2-thiaphosphorin derivatives (5 and 6) and 6-phenyl-5,6-thiaphosphabicyclo[2.2.2]oct-2-ene 6-sulfide (14), respectively. Reaction of 2,3-diphenylbutadiene with phenylphosphinothioylidene afforded
在几种 1,3-二烯存在下,苯基膦酸和苯基硫代膦酰二氯化物用镁脱氯,分别生成苯基亚膦基和苯基亚膦硫基。苯基亚膦硫亚基与 2,3-二甲基丁二烯和 1,3-环己二烯的反应得到 Diels-Alder 型反应产物,即 3,6-二氢-1,2-硫代膦衍生物(5 和 6)和 6-苯基-5,分别为 6-thiaphosphabicyclo[2.2.2]oct-2-ene 6-sulfide (14)。2,3-二苯基丁二烯与苯基亚膦硫亚基反应得到 1,2,4,5-四苯基-1,2,3,6-四氢-1,2-二膦 1,2-二硫化物 (10),而与苯基亚膦基反应得到 1 ,3,4-triphenyl-3-phospholene 1-oxide (12)。已经讨论了这些反应的差异。
