Witryna5 lip 2024 · Carboxylic acids will react with alcohols and amines following a similar pattern. In both cases, the –OH group of the carboxylic acid will be replaced by a different group to form either an ester or an amide, with water formed as a by-product. When the reaction involves an alcohol, the –OH of the acid is replaced by the –OR' of the alcohol. Witryna13 lis 2024 · Contrary to uranium imide chemistry, traditional and routine synthesis protocols seem less viable for rare-earth metal imide complexes. The present review puts its main emphasis on identifying reaction pathways currently available/elaborated for the generation of [An NR] and [Ln NR] moieties. We also address the intriguing …
