Triphenylmethane or triphenyl methane (sometimes also known as Tritan), is the hydrocarbon with the formula (C 6 H 5) 3 CH. This colorless solid is soluble in nonpolar organic solvents and not in water. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display ...
After the German chemist August Kekulé and his Belgian student Antoine Paul Nicolas Franchimont (1844–1919) first synthesized triphenylmethane in 1872, [2] the Russian doctoral student Walerius Hemilian (1851–1914) first synthesized triphenylmethanol in 1874 by reacting triphenylmethyl bromide with water as well as by oxidizing triphenylmethane.
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. [ 2 ] Gomberg was able to distinguish this compound from triphenylmethane ( elemental analysis was not an option given the small differences in the hydrogen fractions of 6.29% ...
Tetraethoxymethane can be used as a solvent and for the alkylation of CH-acidic compounds (e.g. phenols and carboxylic acids).In addition, it reacts with amines, enol ethers and sulfonamides, [12] whereby spiro compounds can also be obtained.
