Molar mass: 278.7754 g/mol Appearance white to yellow solid ... Triphenylmethyl chloride or trityl chloride (TrCl) is a white solid with the chemical formula C 19 H ...
Triphenylmethane was first synthesized in 1872 by the German chemist August Kekulé and his Dutch student Antoine Paul Nicolas Franchimont (1844–1919) by heating diphenylmercury (Hg(C 6 H 5) 2, Quecksilberdiphenyl) with benzal chloride (C 6 H 5 CHCl 2, Benzylenchlorid).
Triphenylmethanol features three phenyl (Ph) rings and an alcohol group bound to a central tetrahedral carbon atom. All three C–Ph bonds are typical of sp 3-sp 2 carbon-carbon bonds with lengths of approximately 1.47 Å, while the C–O bond length is approximately 1.42 Å.
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
It is the thiol derivative of the bulky substituent triphenylmethyl (called trityl). [1] [2] The compound forms a number of unusual derivatives that are more stable than less bulky analogues. The sulfenyl chloride (C 6 H 5) 3 CSCl is obtained from the thiol with sulfuryl chloride. It in turn reacts with ammonia to form the sulfenamide (C 6 H 5 ...
The triphenylmethyl radical can be prepared by homolysis of triphenylmethyl chloride 1 by a metal like silver or zinc in benzene or diethyl ether. The radical 2 forms a chemical equilibrium with the quinoid-type dimer 3 (Gomberg's dimer). In benzene the concentration of the radical is 2%. [3] Triphenylmethyl radical
Triphenylcarbenium Space-filling model of the Ph 3 C + ion. In chemistry, triphenylcarbenium, [1] triphenylmethyl cation, tritylium , [2] or trityl cation is an ion with formula [C 19 H 15] + or (C 6 H 5) 3 C +, consisting of a carbon atom with a positive charge connected to three phenyl groups.
Tropylium tetrafluoroborate is an organic compound with the formula [C 7 H 7] + [BF 4] −.Containing the tropylium cation and the non-coordinating tetrafluoroborate counteranion, tropylium tetrafluoroborate is a rare example of a readily isolable carbocation.
