Tw. Bastock et al., COMPETITIVE ALKYLATION REACTIONS IN THE MONTMORILLONITE-FECL3-CATALYZED ACYLATION OF AROMATIC SUBSTRATES, Journal of chemical research. Synopses, (3), 1994, pp. 104-105
The acid-treated montmorillonite-FeCl3-catalysed reactions of acyl chl
orides with aromatic substrates can result in the formation of chloros
tyrene products as well as the expected acylated products.
