Abstract
We disclose an efficient nickel catalytic system for expediting the coupling of alkynes with fluoroalkyl hydrazones and boronic acids, thus facilitating the synthesis of stereospecific α-fluoroalkyl-alkene derivatives. 3H-Pyrazoles might be involved as key intermediates through a nitrogen-releasing process, enabling subsequent coupling with boronic acids to afford 1,2-difunctional alkenes in a highly efficient and step-economical fashion. This tandem platform demonstrates broad functional group tolerance, including complex natural products and drug-like molecules.
