Procedure

In a heavy-walled tube equipped with a magnetic stir bar, ester (5) (1.18 g, 4.00 mmol, 1.0 equiv.) and H2PtCl6.6H2O (21 mg, 0.14 mmol, 1.0 mol. %) were loaded. The tube was transferred into a glovebox and HSiCl3 (0.82 mL, 8.04 mmol, 2.0 equiv.) was added to the solution. The tube was tightly fastened then removed from the glovebox. The resulting solution was stirred at 80° C. for 22 h behind a protecting shield. Purification was achieved by Kugelrohr distillation under high vacuum and provided 1.16 g (67%) of TTTA (6) as a colorless oil; bp=170-180° C. (0.15 Torr); 1H NMR (400 MHz, CDCl3) δ 4.45 (q, J=8.5 Hz, 2H), 2.41 (t, J=7.4 Hz, 2H), 1.72-1.55 (m, 4H), 1.45-1.22 (m, 18H); 13C NMR (100 MHz, CDCl3) δ 172.4, 123.3 (q, J=275.8 Hz), 60.3 (q, J=36.4 Hz), 33.9, 32.0, 29.8, 29.7, 29.6, 29.5, 29.4, 29.2, 29.1, 24.9, 24.5, 22.5.
