Synthesis of 1-benzyl-1H-indene

Preparation of 1-benzyl-1H-indene (1-benzylindene; 1H-indene, 1-phenylmethyl)

1-Benzyl-1H-indene is prepared by reacting aluminum amalgam, prepared by Wislicenus’ method (H. Wislicenus, J . Prakt. Chem., 54, 18 (1896)) and moist ether by allowing to react with the 1-benzylidene-1H-indene for 1-2 days with occasional addition of a little water.

Preparation of 1-benzyl-1H-indene (1-benzylindene; 1H-indene, 1-phenylmethyl)

5 g of 1-benzylideneindene is dissolved in ether and treated, until decolorized, with freshly prepared 15 g of aluminum amalgam with occasional addition of a little water. The reduction process requires 6-24 h. The obtained mixture is filtered, the residue is well washed with ether, the solution is dried and freed from ether by distillation, and the residue is fractionated. The resulting 1-benzyl-1H-indene distils at 183-185° C at 13 mm.
