Improved selectivity in the chloromethylation of alkylbenzenes in the presence of quaternary ammonium salts

Article abstract of DOI:10.1055/s-1991-26630

Improved yield and selectivity in the chloromethylation of aromatic hydrocarbons in the presence of several phase transfer catalysts are reported. The best yield (98%) and selectivity (p/o ratio = 8.2) were obtained in the chloromethylation of cumene in the presence of a classical micellar catalyst.
