[Ph2P(O)CH2CH2N(R)· C(O)CH2]2O, where R Me, Bu, Oct, were synthesized by reaction of diglycolyl chloride with N-alkyl-N-(2-diphenylphosphinylethyl)amines Ph2P(O)CH2CH2NHR obtained by reacting diphenyl(2-phenoxyethyl)phosphine oxide with primary alkylamines in DMSO in the presence of an aqueous alkali. Structure of the prepared compounds was studied by 1H, 13C, and 31P NMR spectroscopy.
摘要 五齿双[ N-烷基-N-(2-二苯基膦基乙基)]二甘酰胺[Ph 2 P(O)CH 2 CH 2 N(R)·C(O)CH 2 ] 2 O,其中R Me,Bu,Oct,通过将二甘醇酰氯与N-烷基-N-(2-二苯基膦基乙基)胺反应制得Ph 2 P(O)CH 2 CH 2 NHR通过在DMSO存在下使二苯基(2-苯氧基乙基)膦氧化物与伯烷基胺反应获得碱水溶液。在1 H,13 C和31 H下研究了所制备化合物的结构1 H NMR光谱。
