"Greener" Friedel-Crafts acylations: a metal- and halogen-free methodology.
Org. Lett. 13(9) , 2232-5, (2011) The utility of methanesulfonic anhydride for promoting the Friedel-Crafts acylation reaction of aryl and alkyl carboxylic acids is disclosed. This reagent allows the preparation of aryl ketones in good yield with minimal waste containing no metallic or haloge... |

Study of regioselective methanesulfonylation of simple aromatics with methanesulfonic anhydride in the presence of zeolite catalysts.
Org. Biomol. Chem. 2(21) , 3150-4, (2004) Regioselective methanesulfonylation of simple aromatics using methanesulfonic anhydride can be achieved over zeolite catalysts. For example, methanesulfonylation of toluene over various cation-exchanged zeolite beta catalysts affords higher para-selectivity i... |
