 The freocrafts alkylation is a chemical reaction that involves the addition of an alkyl group to an arine or heteroarine molecule. This process has been widely studied for decades due to its versatility and efficiency. Recently, researchers have developed more environmentally-friendly methods for performing these reactions by replacing toxic substances with less harmful ones such as benzyl halide derivatives. These new methods use catalytic amounts of a Lewis acid to produce a variety of products from benzyl-propagyl- and halyl alcohol derivatives, as well as styrene derivatives. Furthermore, these methods require lower catalyst loads than traditional freocrafts conditions, making them more economical and environmentally friendly.
