  摘要：

  The synthesis of three novel 5-methylfuryl-containing Schiff bases: N,N'-bis(5-methylfurfurylidene)-4,4'-diaminodiphenylmethane, N,N'bis(5-methylfurfurylidene)-1,4-phenylenediamine, and N,N'-bis(5-methylfurfurylidene)benzidine and the corresponding bis(aminophosphonates) derived from them, 4,4'-bis{N-methyl(diethoxy-phosponyl)-1-[(5-methyl)-2-furyl]}diaminodiphenylmethane, 1,4-bis {N-methyl(diethoxyphosphonyl)-1-[(5-methyl)-2-furyl]}diaminobenzene, and bis{N-methyl(diethoxyphosphonyl)-1-[(5-methyl)-2-furyl]}-benzidine, is reported. The compounds have been characterized by elemental analysis, TLC, JR, and NMR (H-1, C-13, and P-31) spectra. For comparison, new C-13 and P-31 NMR data of three furyl-containing analogues of the above bis(aminophosphonates) are also regarded. The NMR studies of the two series of bis(aminophosphonates) reveal the presence of one diastereomer (meso or racemic form).

  Provided herein are methods for preparing alkylfurans, such as 2,5-dialkylfurans and 2-alkylfurans. Furfural or 5-alkylfurfural can be reacted with aniline or diaminobenzene, or derivatives thereof, to form the corresponding imine, which can be reduced to form alkylfurans and to regenerate the aniline or diaminobenzene, or derivatives thereof. The alkylfuran may be, for example, 2,5-dimethylfuran or 2-methylfuran.

  本文提供了制备烷基呋喃的方法，例如2,5-二烷基呋喃和2-烷基呋喃。糠醛或5-烷基糠醛可以与苯胺或二氨基苯等衍生物反应，形成相应的亚胺，亚胺可以还原成烷基呋喃，并再生苯胺或二氨基苯等衍生物。烷基呋喃可以是例如2,5-二甲基呋喃或2-甲基呋喃。
