WebAcylation means substituting an acyl group into something – in this case, into a benzene ring. The most commonly used acyl group is CH 3 CO-. This is called the ethanoyl group. In the example which follows we are substituting a CH 3 CO- group into the ring, but you could equally well use any other alkyl group instead of the CH 3.
