    • A typical experimental procedure is as follows; to a mixture of NHPI (0.1 mmol) and Co(acac)2 (50 μmol) were added 1a (5 mmol) and 2a (1 mmol, The reaction mixture was stirred at 75°C for 15 h under dioxygen. The product was isolated by column chromatography (230-400 mesh silica gel, n-hexane:ethyl acetate, 5-20:1, The yields of products were estimated from the peak areas based on the internal standard technique using GC. The prodcuts 3 and 4 were reported previously.6,7 Data for 5: IR (KBr, cm-1, 3589, 2994, 1792, 1393, 1252, 1142, 1075, 971. 1HNMR (270 MHz, CD3OD, δ 2.80 (s, 1H, 0.94 (s, 3H, 0.84 (s, 3H, 0.81 (s, 3H, 0.79 (s, 3H, 13C NMR 68 MHz, CD3OD, δ 172.7, 170.4, 85.9, 83.0, 82.1, 56.5, 30.1, 24.6, 24.6, 23.6.
