Chemistry 241 at DC

Wednesday, May 02, 2007. Today was the final day of new material and it ended with a bang - the Friedel-Crafts alkylation and acylation reactions. These reactions involve the formation of C-C bond during EAS reactions. The carbon is made electrophilic by the reaction between an alkyl or acyl halide and a trihalo aluminum compound. The acylation is a better reaction (generally) than the alkylation because the resultant C is stabilized by resonance. Tuesday, May 01, 2007. Thursday, April 26, 2007. Today wa...
