Acidic ionic liquid was used as a metal-free and recyclable catalyst for the synthesis of polysubstitutedolefins by activating of ethers in dimethyl carbonate as a green solvent. Density functional theory (DFT) calculations showed a hydrogen bonding effect during the reaction.

A convenient method for synthesizing aryl-containing trisubstituted alkenes through directalkylation of alkenes was successfully achieved under solvent-free and catalyst-free conditions. The absence of solvents was found to be crucial in initiating this sequence. Moreover, this protocol stands out due to its minimal waste production and straightforward operation. The radical capture experiment provided
