View all references ] The disadvantages associated with the classical procedures include the use of toxic acid chlorides or acid anhydrates as acylating agents and an excess amount of aluminum trichloride as a Lewis acid, which entails environment pollution and tedious workup. To minimize this problem, some catalytic Friedel–Crafts acylations have been developed recently. [ 2 2. (a) Olah , GA ; Malhotra , R. ; Narang , SC ; Olah , JA Heterogenous catalysis by solid ...
