The ruthenium complex of formula 1.2 (0.309 g; 0.344 mmol; 1 eq.) (also called [(5-cyclopentyl-2-mesityl)-imidazo-1-lidene]dichloro(3-phenyl-1H-inden-1-ylidene)(tricyclohexylphospine)ruthenium) was reacted with the styrenyl ether of formula 2H (65 mg; 0.37 mmol; 1.1 eq.). The reaction is carried out in the presence of dichloromethane (DCM; 3.5 mL) and copper(l) chloride (CuCl; 36.8 mg; 0.37 mmol; 1.1 eq.), at 35 C. for 5 hours.After purification on a silica gel column, the alkylidene ruthenium complex of formula 1.5 is obtained (89 mg; 0.158 mmol; 45%):in which Mes represents the mesityl group.The reaction scheme is shown below:In this reaction scheme, Cy3P represents tricyclohexylphosphine, Mes represents the mesityl group, and Ph represents a phenyl group.The scheme shows that the product obtained, at a yield of 45%, is the alkylidene ruthenium complex of formula 1.5.NMR1H (400 MHz, CDCl3): 16.42 (s, 1H); 7.50 (m, 1H); 7.27 (m, 1H); 7.10 (s, 2H); 7.01 (m, 1H); 6.95 (m, 2H); 6.88 (d, J=2 Hz, 1H); 5.96, (q, J=7.5 Hz, 1H); 5.18 (sept., J=6.21 Hz, 1H);13C (100 MHz, CDCl3): 172.2; 152.7; 144.5; 139.6; 137.6; 137.4; 129.3; 129.0; 125.0; 122.7; 122.4; 118.5; 113.0; 75.1; 64.2; 34.4; 24.7; 22.0; 21.4; 18.2.The alkylidene ruthenium complex of formula 1.5 was isolated and was submitted to various studies.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 67191-35-9.
