Reactions of dialkyl phosphites (DAP, 1a, b) and trialkyl phosphites (TAP, 2a, b) with the α,β-unsaturated nitriles (3a, b and 4a, b) as well as with anils (5a and 6) derived from aromatic aldehydes (vanillin and/or piperonal) are reported. Structures of the new phosphonate products (cf. 7,8,15,16 and 17) were based upon compatible elementary and spectroscopic results Tervalent phosphites (TAP, 2a, b) and
摘要 亚磷酸二烷基酯 (DAP, 1a, b) 和亚磷酸三烷基酯 (TAP, 2a, b) 与 α,β-不饱和腈(3a, b 和 4a, b)以及衍生的苯胺(5a 和 6)的反应来自芳香醛(香兰素和/或胡椒醛)的报道。新膦酸酯产品(参见 7、8、15、16 和 17)的结构基于兼容的元素和光谱结果 三价亚磷酸酯(TAP、2a、b)和三苯基膦将香草醛肟(5b)转化为 4-羟基 - 3-甲氧基苄腈 (19)。还假设了可能的反应机制来解释化合物 7a-d、8a、b 和 19 的形成。
