Scandium chloride (ScClj) Sc " + 3C1 —> ScCl. As mentioned, this compound is used in an electrolytic procedure to produce metallic scandium. [Pg.90]

Scandium chloride, ScCla, begins to sublime at 850°. Aluminum chloride begins to sublime above 100°. In aqueous solution the salt is hydrolyzed. [Pg.680]

A partially soluble polyallylscandium triflamide ditriflate 45 was prepared and used to catalyze a three-component coupling reaction.67 An aldehyde, an aromatic amine, and an alkene were mixed in the presence of the catalyst to afford tetrahydroquinolines (equation 17). The catalyst was recovered from the reaction mixtures by precipitation with hexane and could be recycled without loss of activity. Another polymer-supported scandium catalyst was prepared by treating Nafion with scandium chloride to afford the Nafion-scandium catalyst 46.68 This catalyst was used in allylation reactions of carbonyl compounds by tetraallyltin (equation 18). It could be easily recovered by filtration and reused without appreciable loss of activity. [Pg.172]

A recent synthesis of anhydrous 80(0104)3 from hydrated scandium chloride proceeds via an orange adduct [Sc(C104)3-0.25Cl206] that loses the CI2O6 in vacuo at 95 °C (see Scheme (2)). [Pg.98]

Grey anhydrous scandium triflate, [Sc(03SCF3)3] (triflate = trifluoromethane sulfonate), has been obtained by dehydration of the hydrate at 190 200 °C the hydrated salt was itself obtained from the reaction of hydrated scandium chloride and dilute triflic acid. [Sc(03SCF3)3], in which triflate is believed to act as a bidentate ligand (similar to perchlorate in 80(004)3), is not isomorphous with the lanthanide analogues. [Pg.99]

Porphyrins, hydroporphyrins, azaporphyrins, phthalocyanines, corroles, corrins, and related macrocycles were discussed in CCC (1987).144 The octaethylporphyrin complexes of scandium were also previously mentioned in CCC (1987).1 The octaethylporphyrin (oep) scandium chloride complex (oep)ScCl, prepared by the reaction of the dilithium porphyrin with ScCl3(thf)3, has proved...

Single crystal X-ray structures of CpDoCp HScCl and CpDoCp HScMe were published. Both molecules showed a similar structure. The Cl complex is one of the very few examples of a di(cyclopentadienyl)scandium chloride without bridging chlorine atoms. This terminal Sc-Cl distance is 2.4574(12) A shorter than in a scandium chloride complex with bridging chlorine atoms like [Cp"2Sc(/r-Cl)]2 with 2.58 A. The scandium metal atom is surrounded by four ligands in a distorted tetrahedral geometry. The coordinated dimethylamino group decreases the Lewis acidity... [Pg.67]

Lewis acid-surfactant combined catalysts (LASCs) are possible solutions to address this issue. LASCs designed from water-compatible Lewis acids are expected to act as surfactants as well as Lewis acids in water. One example of LASCs that can be readily prepared from scandium chloride and sodium trisdodecylsulfate in water is scandium trisdodecylsulfate ([ScCDSIj]), shown in Figure... [Pg.251]
