Enol ethers corresponding to the title compounds am oxidized at a platinum or glassy carbon anode in acetonitrile. In poorly nucleophilic media, the electrochemical reaction principally leads to dimers and oligomers due to the electrophilic attack of transient cations on the aromatic substituents of

## Abstract CuBr/FeCl~3~ Catalysis as a novel and efficient method has been developed for the preparation of new aryl propargyl imine ether derivatives __via__ Cο£ΏH activation of aryl propargyl ethers, followed by reaction with imines generated from aldehydes and amines.
The electrochemical, Pd-catalyzed cleavage of the C-O bond of allyl aryl ethers has been examined; the method constitutes a new alternative for allyl ether deprotection. The allyl transfer from the allyl ether to the carbonyl group in 2-allyloxy benzaldehydes is reported and is an example of allyl-P
