A new homocoupling methodology mediated by a novel combination of CuCl-2,2'-dipyridyl and its application to the synthesis of substituted polyfluorinated alka-2,4-dienes are described.
The consecutive reaction of bis [2,2,2-trifluoroethyl ] phosphite and its application to the one-pot synthesis of 3-cyano-β,γ-un-saturated nitriles with exclusive or predominant E-selectivity (E:Z = 100-85:0-15) and excellent yields (94%-99%) are described.
