  • The α-bromoketal was not isolated, but only identified in the crude mixture by 'H and C NMR spectroscopy. 'H NMR (300 MHz, CDC13) 8 : 3.37 (d, 1H, J= 5.5); 3.40 (s, 6H); 4.55 (t, 2H, J= 5.5). C NMR (75.5 MHz, CDC13) 5 : 31.4 (CH2); 51.8 (CH3); 53.8 (CH3); 103.0 (CH). These data are very similar to those observed for the adduct of NBS to ethylvinylether in methanol
