The addition reaction of acid chlorides with terminalalkynes to afford β-chloro-α,β-unsaturated ketones using ZnO as catalyst has been studied under solvent-free conditions. All the reactions were...
iron(III)-catalyzed synthesis of substituted β-chlorovinyl ketones and α,β-alkynyl ketones from terminal and silyl-substituted alkynes with acidchlorides, respectively, is described. This method features easily available starting materials, a cheap and non-toxic catalyst, simple manipulation and mild reaction conditions. Evidence shows that the catalytic addition of the acidchloride to a terminal alkyne
