Preparation of Diphenylmethane: it is prepared by the reaction of benzyl chloride with benzene in the presence of a Lewis acid such as aluminium trichloride: C6H5CH2Cl + C6H6 → (C6H5)2CH2 + HCl. In addition, it also can be prepared by diphenylmethanol. This reaction will need reagents Ph2SiHCl and InCl3, and solvent CH2Cl2. The reaction time is 2 hours at reaction temperature of 20 °C. The yield is about 97%.
