A method of carrying out a metathesis reaction includes the combination of at least one alkene or non conjugated diene with a Ruthenium-based catalyst with an cyclic(alkyl)(amino)carbene ligand to form a reaction mixture, heating the reaction mixture to a temperature of 100° C. or greater in the absence of a solvent in bulk conditions, and mechanically stirring the reaction mixture. The reaction can be an ADMET, ROMP, a metathesis ring-closure or an olefin exchange reaction.
