Stereoselective cyanation of β-bromo-β-fluorostyrenes using potassium cyanide and promoted by (CH3CN)4Cu+ BF4−
摘要:
A general method for the synthesis of alpha-fluorocinnamonitrile based on the stereoselective reaction between beta-bromo-beta-fluorostyrene and potassium cyanide, promoted by (CH3CN)(4)Cu+ BF4- in 1-methyl-2-pyrrolidinone (NMP), is described. (C) 2011 Elsevier Ltd. All rights reserved.
