The reaction of substituted benzyl chlorides with 1,4-di-tert-butylbenzene in the presence of titanium chloride leads to the formation of 2,5-di-tert-butyldiphenylmethane and 3- and 4-tert-butyldiphenylmethanes.The amount of 4-tert-butyldiphenylmethane, formed through ipso substitution of the tert-butyl group, depends on the nature of the substituents in the benzyl chloride and varies in the order 2-Cl > 4-Cl > H >4-CH3.Only the 3,5-di-tert-butyl-2- and 3,5-di-tert-butyl-4-chlorodiphenylmethanes, i.e., the products from ipso substitution of the tert-butyl group, are formed during the benzylation of 1,3,5-tri-tert-butylbenzene with 2- and 4-chlorobenzyl chloride.
