Tetraphenylmethane is an organic compound consisting of a methane core with four phenyl substituents. It was first synthesized by Moses Gomberg in 1898.Gomberg’s classical organic synthesis in scheme 1 starts by reacting triphenylmethylbromide 1 with phenylhydrazine 2 to the hydrazine 3. Oxidation with nitrous acid then produces the azo compound 4 from which on heating above the melting point nitrogen gas evolves with formation of tetraphenylmethane 5.Scheme 1.
