A New Synthetic Route to Aromatic Gyloxals
Mahato, S. B.,Podder, G.,Maitra, S. K.
, p. 1263 (2007/10/02)
Dichloroacylation of toluene, o- and m- xylenes, chloro- and bromo-benzenes and m-chlorotoluene under Friedel-Crafts conditions leads to the corresponding chloroketones (Ia-f) which on controlled hydrolysis afford the glyoxals (IIa-f) respectively.
