The friedel-crafts reaction

WebWhy is a Friedel-Crafts acylation followed by complete carbonyl reduction often preferable to direct alkylation of the aromatic ring? The reaction is more controlled since polysubstitution will not occur Acyl groups have a different directing ability compared to alkyl groups; they therefore give access to different substitution patterns
