Electrochemical Partial Fluorination of Ethyl Cinnamates and Cinnamonitrile.

Abstract

Halogenation O 0235Electrochemical Partial Fluorination of Ethyl Cinnamates and Cinnamonitrile.-The selective electrochemical fluorination of ethyl cinnamates and cinnamonitrile under controlled anode potentials using ammonium fluorides as supporting electrolytes and fluorine sources yields 2,3-difluoro-3-arylpropionates and 2,3-difluoro-3-arylpropionitrile, resp., as a mixture of two diastereomers. -(DINOIU*, V.; KANNO, K.; FUKUHARA, T.; YONEDA, N.; Rev.
