    • Typical Experimental Procedure for RCM-Dehydration, Synthesis of 4-Acetoxymethyl-2-methylbiphenyl (4e) To a solution of 1,4,7-trien-3-ol 3e (43.0 mg, 0.150 mmol) in CH2Cl2 (15 mL) was added 7.5 mol% of catalyst 10 (9.3 mg, 0.011 mmol) in one portion under nitrogen. After stirring for 2 h at 40°C, the reaction mixture was treated with silica gel(excess) and stirred for 1 h at r.t. The mixture was passed through Celite® and the filtrate was concentrated under reduced pressure. Purification by PTLC on silica gel (hexane-EtOAc, 5:1) gave 4e (31.5 mg, 0.131 mmol, 87, 1H NMR (CDCl3, δ, 2.12 (s, 3 H, 2.29 (s, 3 H, 5.12 (s, 2 H, 7.22-7.36 (m, 6 H, 7.41 (t, J, 7.7 Hz, 2 H, 13C NMR CDCl3, δ, 20.42, 21.06, 66.19, 125.74, 126.91, 128.10, 129.09, 130.05, 130.30, 134.77, 135.72, 141.42, 141.98, 170.95.
