本文研究了酸性亚磷酸酯与α-芳基-β-硝基烯烃在三甲基氯硅烷和缚酸剂存在下的Arbuzov-Michael反应。不需制备硅烷化的亚磷酸酯,即可得到产率高的I_(a-n),其结构由元素分析、IR、~1H NMR和MS证实。这类分子中磷原子上的O,O-二烷基为磁不等价基团的结论亦为X-射线晶体结构分析所证实。
In this paper, the Arbuzov-Michael reaction of acidic phosphite with α-aryl-β-nitroalkenes in the presence of trimethylchlorosilane and acid-binding agent has been studied. The yield of I_ (a-n) was obtained without the preparation of silylated phosphite. The structure was confirmed by elemental analysis, IR, ~ 1H NMR and MS. The conclusion that the O, O-dialkyl on the phosphorus atom in these molecules is a magnetic inequivalent group is also confirmed by X-ray crystal structure analysis.
