WebSince the discovery of the triphenylmethyl (trityl) cation 120 years ago, a variety of aromatic cations having various colors and luminescence properties have been rigorously studied. Many,... WebStep 3: Stability of triphenylmethyl cation. Here in triphenylmethyl cation, positive charge is on C-atom which is next to benzene (phenyl group) ring. This phenyl group helps in the delocalization of positive charge in the ring which makes them stable carbocation. Also there are three phenyl group which make further stable this triphenylmethyl ...

WebJul 17, 2006 · The decomposition reaction of a solution of (o-methoxymethyl)triphenylmethyl cation 6 results in the formation of α,α-diphenyldihydroisobenzofuran 7. This, on further treatment with acid, gets converted into 9-phenylanthracene 8, thus exemplifying side-chain cyclization (Scheme 2). In chemistry, triphenylcarbenium, triphenylmethyl cation, tritylium , or trityl cation is an ion with formula [C19H15] or (C6H5)3C , consisting of a carbon atom with a positive charge connected to three phenyl groups. It is a charged version of the triphenylmethyl radical (C6H5)3C•.

WebCrystal violet is another triphenylmethane derivative for which a tautomeric and pH-dependent equilibrium exists between the triphenylmethyl cation and its quinoidal form (Fig. 4.16). In acid medium, the quinoidal form leads to mono and dicationic forms by the protonation on nitrogen atoms (Fig. 4.17). The pH range for Crystal violet is 0.0–1.8. WebFeb 23, 2024 · 1. Introduction Since the discovery of the first carbocation—triphenylmethyl cation—in 1901, 1,2 the versatile reactivities of diverse carbocations have garnered significant attention from the synthetic community. This has resulted in flourishing of carbocation chemistry in synthetic method development and natural product synthesis … WebTriphenylmethyl hexafluorophosphate (also triphenylcarbenium hexafluorophosphate, trityl hexafluorophosphate, or tritylium hexafluorophosphate) is an organic salt with the formula [ (C6H5)3C]+[PF6]−, consisting of the triphenylcarbenium cation [ (C6H5)3C]+ and the hexafluorophosphate anion [PF6]−.
