Procedure

A mixture of TMIT (1.0 g, 6.33 mmol), 2-ethylhexyl acrylate (1.16 g, 6.33 mmol) and cesium carbonate (1.0 g, 3.3 mmol) in acetonitrile (15 mL) was stirred at room temperature for 24 h. The reaction mixture was filtered to separate solid cesium carbonate and solvent was evaporated from the filtrate to obtain the product as a colorless oil (1.9 g, 88 %). IR: 3325, 2961, 1732, 1595, 1480 cm31 1; 1H NMR (CDCl3, 500 MHz): δ3.96 (overlapping d, 2 H), 3.83 (t, 1.72 H), 3.22 (t, 0.28 H), 2.82 (t, 1.72 H), 2.71 (t, 0.28 H), 1.91 (bs, 1H), 1.42 (s, 6 H), 1.40 (s, 6H), 1.35-1.20 (m, 8 H), 0.85 (overlapping t, 6 H) ppm; 13C NMR (CDCl3, 125 MHz): δ205.8, 173.6, 171.9, 171.3, 130.2, 128.5, 88.7, 82.9, 70.35, 69.6, 67.2, 66.9, 66.8, 40.6, 38.6, 33.9, 31.4, 30.26, 30.21, 28.79, 28.71, 28.23, 25.8, 23.64, 22.83, 13.9, 10.9 ppm.
