Palladium-Catalyzed Coupling Reaction of Fluoroalkylated Propargyl Mesylates with Organozinc Reagents: Novel Synthesis of Optically Active Fluorine-Containing Trisubstituted Allenes
presence of 5 mol% of tetrakis(triphenylphosphine)palladium(0), the reaction of chiral fluorinated propargyl mesylates with a variety of organozincreagents proceeded smoothly in a highly stereoselective fashion to give the corresponding optically active fluorine-containing trisubstituted allenes in good yields without any loss of optical purity through the reaction.
