摘　　要：本文报道用亚磷酸三苯酯或连二亚硫酸钠使氧化三苯胂还原为三苯胂的两个新方法.此法简便,反应条件温和,得率高,具有实用价值.用^(31)PNMR 研究了亚磷酸三苯酯和三苯膦对于氧化三苯胂、吡啶-N-氧化物、二甲亚砜的脱氧活性,并研究了钼配合物 Mo^(?)O_2[S_2CN(C_2H_5)_2]_2作为催化剂时对三苯膦和亚磷酸三苯酯脱氧活性的影响,讨论了上述反应的机理.Two new and convenient methods using triphenylphosphite or sodium dithioniteto deoxygenate triphenylarsine oxide to triphenylarsine are described.^(31)P NMR spectrawas used to study the reactivity of triphenylphosphite and triphenylphosphine indeoxygenating triphenylarsine oxide,pyridine-N-oxide and dimethylsulfoxide and theinfluence of complex MoO_2(S_2CN(C_2H_5)_2)_2 on the reactivity.The mechanisms of theabove reactions are briefly discussed.
