Ruthenium-catalyzed ene-yne cross-metathesis is performed with stoichiometric proportions of terminal olefins and alkynes. This is made possible by the continuous addition of the alkyne to the reaction mixture. The protocol allows the ene-yne cross-metathesis reaction to be carried out with long-chain terminal olefins and in a one-pot fashion with internal olefins after shortening by ethenolysis. The efficient conversion of renewable unsaturated fatty esters from bioresources into valuable conjugated 1,3-dienes of interest for further transformations is performed using this technique under mild conditions in dimethyl carbonate; an ecofriendly solvent. Environmentally ene-yne: A ruthenium-catalyzed ene-yne cross-metathesis reaction is performed with stoichiometric amounts of terminal olefins and alkynes. The alkyne is added to the reaction mixture continuously. The protocol allows ene-yne cross-metathesis reaction to be carried out with long-chain terminal olefins and with internal olefins after shortening by ethenolysis in dimethyl carbonate as solvent.

Two little known chemical methods, the "Competition Constant Method" and the production of "Ligand Concentration/ Product Yield Diagrams", are suitable for the characterisation and identification of allyl and crotyl transition metal species prepared in so
