3-Trifluoroacetyl-quinolin-2(1)-ones as Carbonyl and Acid Surrogates in the Passerini-/Ugi-Type Reaction.

Herein, we report tailored 3-trifluoroacetyl-quinolin-2(1)-ones () as carbonyl and acid surrogates in Passerini- and Ugi-type reactions for the synthesis of α-trifluoromethyl-α-hydroxy carboxamides () and α-trifluoromethyl α-amino acids () in high yields, respectively. The reaction proceeds under mild reaction conditions via an exocyclic carboximidate intermediate (). The amide group in compound acts as an acid component as well as a reversible oxygen nucleophile to facilitate the reaction.

Sustainable and cost-effective ternary electrolyte EtNHCl-AlCl-Mg(DEP) for high-performance rechargeable magnesium batteries.

Cost-effective and sustainable battery materials for large-scale batteries are the need of the hour to garner renewable energy with high-performance metal battery technologies. Here, we report the high-performance and long cycle life electrolyte prepared from low-cost triethylamine hydrochloride (EtNHCl) and aluminum chloride (AlCl) termed as (TA) with different concentrations of magnesium diethylphosphate (Mg(DEP)) salt. The optimized ratio of the 0.
