ACTION DU DIETHYLPHOSPHITE ET DE LA P-CHLORODIPHENYLPHOSPHINE SUR LES β-ACYLACRYLATES ET LES 2-ENE-1,4-DIONES: SYNTHESE DE γβ'-CETOESTERPHOSPHONATES ET DE 3-(DIPHENYLPHOSPHINEOXDE)-FURANES

p-chlorodiphenylphosphine react with β-acylacrylates to give γ,β'-ketoester-phosphonates 2 and 2′. When reacted with 2-ene-1,4-diones, in the same conditions, p-chlorodiphenylphosphine leads directely to 3-(diphenylphosphineoxide)-furans 4. The structure of all obtained products is confirmed by NMR and IR spectroscopy.
摘要 亚磷酸二乙酯和对氯二苯基膦与 β-丙烯酸酯反应生成 γ,β'-酮酯膦酸酯 2 和 2'。当与 2-ene-1,4-二酮反应时,在相同条件下,对氯二苯基膦直接生成 3-(二苯基氧化膦)-呋喃 4。所有所得产物的结构均通过 NMR 和 IR 光谱证实。
