 The Friedel-Krafts alkylation is a chemical reaction between an arene and an alkyl halide, where the arene is converted into an alkylated derivative. This process has been improved upon by using catalytic amounts of a Lewis acid, such as benzyl halides, propagal alcohol, or allyl alcohol, instead of toxic benzyl halides. Furthermore, low catalyst loadings are required for a wide range of products. This review focuses on the use of these environmentally friendly substrates, as well as the first diastereoselective and enantio-selective Friedel-Krafts-type alkylations.
