A novel electrochemical partial fluorination (ECF) of conjugated esters took place and vic-difluorinated products were obtained. The electrolysis was performed under controlled anode potentials. The effects of the supporting electrolyte of Et3N–nHF and solvent on these reactions were examined.
发生了共轭酯的新型电化学部分氟化(ECF),并获得了vic-二氟化产物。电解在受控的阳极电势下进行。研究了Et 3 N– n HF的支持电解质和溶剂对这些反应的影响。
2,4-Alkadienoic acid derivatives such as ester, amide, and nitrile were converted to the corresponding 4-oxo-2-alkenoic acid derivatives in good yields by the oxygenation with oxygen and triethylsilane in the presence of a catalytic amount of [5,10,15,20-tetra(2,6-dichlorophenyl)porphinato]cobalt(II) followed by acetylation.
