Abstract
"The extraordinary instability of such an "ion" accounts for many of the peculiarities of organic reactions" - Franck C. Whitmore (1932). This statement from Whitmore came in a period where carbocations began to be considered as intermediates in reactions. Ninety years later, pointing at the strong knowledge acquired from the contributions of famous organic chemists, carbocations are very well known reaction intermediates. Among them, destabilized carbocations - carbocations substituted with electron-withdrawing groups - are, however, still predestined to be transient species and sometimes considered as exotic ones. Among them, the CF3-substituted carbocations, frequently suggested to be involved in synthetic transformations but rarely considered as affordable intermediates for synthetic purposes, have long been investigated. This review highlights recent and past reports focusing on their study and potential in modern synthetic transformations.

Abstract
Trimethylsilyl ethers of 1,5-diaryl-3-(trifluoromethyl)-pent-1-en-4-yn-3-oles [Ar-C≡C-C(CF3)(OSiMe3)-CH═CH-Ar'] in the superacid TfOH give rise to reactive conjugated CF3-allylic-propargylic cations [Ar-C≡C-C+(CF3)-CH═CH-Ar']. These species react with arenes in the presence of 1.5 equiv of TfOH forming regio- and stereoselectively E-1,1,5-triaryl-3-(trifluoromethyl)-pent-2-en-4-ynes [Ar-C≡C-C(CF3)═CH-CHAr'(Ar″)] in good yields. In the excess of TfOH, these CF3-pentenynes are further intramolecularly cyclized into CF3-bicyclic dihydroanthracene derivatives ("helicopter"-like molecules). The CF3-pentenynes may also react with arenes, as external nucleophiles, leading to CF3-indenes. These two main reaction pathways depend on internal nucleophilicity of aryl substituents in CF3-pentenynes and external nucleophilicity of aromatic molecules. Plausible cationic reaction mechanisms have been discussed. CF3-bicyclic dihydroanthracene derivatives have been studied regarding their cytotoxicity and virus-inhibiting activity against influenza virus A/Puerto Rico/8/34 (H1N1) in MDCK cell line.

Abstract
Protonation of oxygen in the side chain of the Me3SiO group (followed by the elimination of Me3SiOH) and protonation of the thiophene ring in 2-chloro(or bromo)-5-(1'-Me3SiO-1'-trifluoromethyl-alkyl)thiophenes in Brønsted superacids (CF3SO3H, FSO3H) gave rise to short-lived and reactive trifluoroalkyl carbocations of the thiophene series. These cations were studied by low-temperature NMR spectroscopy in the superacids, which shed light on their reactivity and reaction mechanisms. The cations may react with (hetero)aromatic π-nucleophiles in various directions, depending on their structures as well as the reaction temperature and time. These transformations resulted in the formation of novel fluoro-organics of the thiophene family, namely, products of arylation of both the thiophene system and its side chain, hydrodehalogenation of halothiophenes, or electrophilic "dimerization".

Abstract
The TfOH-mediated reactions of 2,4-diaryl-1,1,1-trifluorobut-3-yn-2-oles (CF3-substituted diaryl propargyl alcohols) with arenes in CH2Cl2 afford 1,3-diaryl-1-CF3-indenes in yields up to 84%. This new process for synthesis of such CF3-indenes is complete at room temperature within one hour. The synthetic potential, scope, and limitations of this reaction were illustrated by more than 70 examples. The proposed reaction mechanism invokes the formation of highly reactive CF3-propargyl cation intermediates that can be trapped at the two mesomeric positions by the intermolecular nucleophilic attack of an arene partner with a subsequent intramolecular ring closure.

Trimethylsilyl ethers of 1,5-diaryl-3-(trifluoromethyl)pent-1-en-4-yn-3-oles in superacid CF3SO3H (TfOH) give rise to the corresponding intermediate CF3-pentenynyl cations. These species react with benzene to afford conjugated CF3-pentenynes, which undergo subsequent cyclization, first, into CF3-cycloheptadienes and, finally, into unusual CF3-"helicopter"-like bicyclic structures.
