“…The accuracy of the systems (uncertainty 1-2 %) has been demonstrated by measurements on other solutions of different electrolytes (e.g. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]).…”

“…Indium(III) chloride is an efficient catalyst for inducing various types of organic reactions, such as synthesis of saccharides [11], Mukaiyama aldol reactions [12], Diels-Alder reactions [13,14], aza-Michael reactions [15], and also in microwave irradiation assisted synthesis [16]; other practical applications of indium(III) chloride includes, for example, its use as a constituent of a photosensitizer used as a photodynamic therapy agent for ocular diseases [17]. However, one of the broadest application of In(III) is as indium tin oxide (ITO), a solid solution with excellent electrical and optical properties [18].…”

Trivalent metal ions have a relevant impact on different kinds of industry; for example, indium(III) and europium(III) ions are of practical importance in the development of new semiconductors and luminescent probes, respectively. Transport properties of ions and salts in aqueous solutions are important physico-chemical parameters allowing a better understanding of the behaviour of these ions in the solution and so, helping to describe better the mechanism of processes taking place in their presence. However, the measurement of those transport properties is complicated due to the occurrence of hydrolysis; that may justify the scarcity of e.g. diffusion data for aqueous solutions of europium(III) and indium(III) chlorides. In this study mutual diffusion coefficients for aqueous solutions of InCl 3 and EuCl 3 in a concentration range from 0.002 mol⋅dm −3 to 0.01 mol⋅dm −3 at 298.15 K are reported. The open-ended conductometric capillary cell was used. The results are discussed on the basis of the Onsager-Fuoss and Pikal models.

“…Multicomponent one‐pot synthesis like α‐amino phosphonates, [7] α‐amino nitriles, [8] α‐amino‐γ‐lactones [9] has been observed employing catalytic amount of InCl 3 . Moreover, InCl 3 mediated construction of sugar fused N ‐aryltetrahydropyridine, [10] antibacterial and antifungal agent 2‐substituted aryl(indolyl)kojic acid derivatives, [11] tetrahydropyridines, [12] amidoalkyl naththols, [13] chremenone‐ and quinoline‐ annulated imidazole derivatives [14] and quinolines [15] using microwave has been accomplished by the multicomponent reaction (MCR) strategy. InCl 3 supported on silica gel has been used for electrophilic amination of arenes with diethyl azodicarboxylate [16] .…”

This review summarizes recent advances of indium trichloride catalyzed synthesis of different organic compounds. It is obvious that InCl3 co‐ordinates with C−C and/or C‐heteroatom multiple bonds and thereby makes them very prone to nucleophilic attack to form a new bond. This Lewis acid catalyst also activates oxiranes to produce aldehydes. Multicomponent synthesis including C−C bond formation reaction and construction of N, O and S‐containing heterocycles are discussed in organic solvents as well as in water. This article highlights recent developments and application of indium(III) chloride as a catalyst in organic synthesis from 2015 to 2020. The mechanism of few important reactions is discussed in detail which will be very useful for the readers.

“…1-Naphthaleneacetic acid and 2naphthoxyacetic acid have been reported to act as plant-growth regulators [6,7] [20], Zinc benzenesulfonate [21], PPA-SiO 2 [22], FeCl 3 .SiO 2 [23], Ce(SO 4 ) 2 [24] and Oxalic acid [25] have been reported. However, some of the reported methods suffer from disadvantages such as prolonged reaction time, higher reaction temperature (>100 o C), low product yields, use of toxic and corrosive solvents, and unconventional methodologies such as microwave or ultrasonic irradiation.…”

Trifluoroacetic acid (TFA) was found as an efficient catalyst for the synthesis of amidoalkyl naphthols from aromatic aldehydes, -naphthol and acetamide/benzamide under solvent free condition at 80 o C. All the synthesized compounds were characterized by IR, 1 H NMR and Mass spectra. The advantages of the new method were good yields, short reaction times, simple work-up, inexpensive and easily available catalyst and economical due to absence of solvent. Therefore, this method could be an attractive alternative to existing methods for the synthesis of biologically important amidoalkyl naphthols.
