참여 물질

반응 단계

7.5 g (0.07 mole) benzaldehyde and 0.3 g (0.004 mole) pyridine are introduced in an apparatus similar to that of example 1. The mixture is brought to 45° C. and 8.5 g (0.043 mole) trichloromethyl chloroformate added drop by drop over 10 minutes. After 2 hours of stirring at 45° it is confirmed by NMR analysis that all the aldehyde has been converted to the α-chlorinated chloroformate with formula: ##STR7##
