  InCl 3 -NaBH 4试剂系统还原活化的共轭烯烃

  摘要：

  乙腈中催化量的氯化铟（III）和硼氢化钠的组合可选择性降低共轭烯烃（如α，α-二氰基烯烃，α，β-不饱和腈，氰基酯，氰基膦酸酯和二羧酸酯）中的碳-碳双键。但是，减少查耳酮几乎没有什么不同。如果将反应混合物用H 2 O淬灭，则它们会还原为饱和酮和醇的混合物，而用MeOH淬灭只会产生饱和醇。

  Synthesis, Molecular Structure, and Spectroscopical Properties of Alkenylphosphonic Derivatives. 1. Vinyl-, Propenyl-, (Bromoalkenyl)-, and (Cyanoalkenyl)phosphonic Compounds

  摘要：

  Several vinyl-, propenyl-, (bromoalkenyl)-, and (cyanoalkenyl)phosphonate derivatives have been synthesized. The (2-cyanovinyl)phosphonates have been obtained with an important improvement in the yield (40% versus 6%). The separation of the E and Z isomers of the cyano derivatives and their hydrolysis to the corresponding phosphonic acids have been studied. The bromination and dehydrobromination of some alkenylphosphonic derivatives have also been studied. Spectroscopical studies from UV, IR, Raman, and H-1, C-13, and P-31 NMR have been performed in most of these derivatives. The C=C/P-O pi conjugation exists but it is weak in all these compounds. Dipole moments and C=C/P=O conformational populations have been calculated theoretically by ab initio methods. The effect of the solvent polarity on the conformational population has been observed by IR spectroscopy disclosing two C=C/P=O conformers. Experimental and theoretical results have been compared, a high level of agreement has been found.
