Rhodium catalysed coupling reaction of myrcene with ethyl acetoacetate in the ionic liquid 1-ethyl-3-methylimidazolium triflimide

The ionic liquid 1-ethyl-3-methylimidazolium triflimide was used successfully as the reaction medium to carry out the rhodium catalysed coupling of myrcene with the active methylene compound ethyl acetoacetate in the presence of TPPMS as the ligand. Coupling product was obtained in 93% isolated yield without any side product formation when a 1:50 ratio of rhodium catalyst/TPPMS was used.
