The reduction of allenyl(diphenyl)phosphine oxides with HSiCl3 or LiAlH4 selectively afforded the corresponding allyl(diphenyl)phosphine oxides. 3-Methylbut-2-en-1-yl(diphenyl)phosphine oxide reacted with AlCl3 to give a mixture of 4,4-dimethyl-1-phenyl-1,2,3,4-tetrahydro-λ5-phosphinoline 1-oxide and 4,4-dimethyl-1-phenyl-1,4-dihydro-λ5-phosphinoline 1-oxide.
用HSiCl 3或LiAlH 4还原烯丙基(二苯基)膦氧化物可选择性地得到相应的烯丙基(二苯基)膦氧化物。3-甲基丁-2-烯-1-基(二苯基)膦氧化物与反应的AlCl 3,得到4,4-二甲基-1-苯基-1,2,3,4-四氢λ的混合物5 -phosphinoline 1氧化物和4,4-二甲基-1-苯基-1,4-二氢-λ 5 -phosphinoline 1-氧化物。
