What product is formed when benzene is treated with the given organic halide in the presence of AlCl3? What carbonyl compounds might you start with in a Grignard synthesis of the following compound? 3-phenyl-3-pentanol You do not have to consider stereoc...
Some examples of Friedel-Crafts types of catalysts include mixtures of AlCl3 and HCl (for which the alkylation process is generally practiced below 135° C. and at sufficient pressure to keep the reactants in the liquid phase), a composite of phosphoric acid and a solid binder material, such...
