Tetraphenylmethane is an organic compound consisting of a methane core with four phenyl substituents. It was first synthesized by Moses Gomberg in 1898.

== Synthesis == Gomberg's classical organic synthesis shown below starts by reacting triphenylmethyl bromide 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. 500px|Gomberg's tetraphenylmethane synthesis
