2-and 3-furoyl chlorides having chloromethyl or butylthiomethyl group in the adjacent position of the furan ring as well as of analogous N-morpholinomethylfuroyl chloride hydrochlorides with triethyl phosphite have been studied. The synthesized chloromethylfuroyl phosphonates have given the corresponding products of nucleophilic substitution in the reactions with sodium azide and potassium thiocyanate
在呋喃环的相邻位置具有氯甲基或丁基硫代甲基的2-和3-糠酰氯的反应以及类似的N研究了亚磷酸三乙酯与吗啉代甲基糠酰氯盐酸盐。在4-氯甲基-3-糠酰基膦酸酯的情况下,合成的氯甲基糠酰基膦酸酯在与叠氮化钠和硫氰酸钾的反应中给出了亲核取代的相应产物。在3-氯甲基-2-糠酰基膦酸酯与叠氮化钠的反应中,PC键的裂解与亲核取代同时发生。硫氰酸钾在与该物质的反应中形成3-硫氰酸根合甲基-2-糠酰基膦酸酯。合成的稳定的呋喃基膦酸酯与共振稳定的膦烷一起进入Wittig反应,得到磷酸化的呋喃基烯烃。如果这些化合物在呋喃环中带有一个氯甲基,它们与叠氮化钠和硫氰酸钾反应,得到相应的亲核取代产物。类似地,在室温下与吗啉反应中获得了氨基甲基衍生物。
