The acetate salt of this element can help catalyze asymmetric Mannich reactions, while the tosylate of this element can catalyze homocoupling of Grignard reagents.
The acetate salt of this element can help catalyze asymmetric Mannich reactions, while the tosylate of this element can catalyze homocoupling of Grignard reagents. Its oxide is often used as the catalyst in the Wolff rearrangement. Sudalai developed catalytic versions of the PrÃ©vost reaction and its Woodward modification in order to minimize its use. The carbonate of this element can convert the most reactive hydroxyl in a compound to a carbonyl, a reaction known as the Fetizon oxidation. Alkyl compounds containing it can be prepared by reacting alkyllead compounds with this element's nitrate, though compounds of this element are generally less thermally stable than corresponding copper compounds. Its oxidation state in its trifluoromethyl cation is +3, a departure from its usual +1 oxidation state seen in compounds such as its insoluble chloride. For 10 points, name this element that precipitates in the presence of an aldehyde in the Tollens test.
