Journal ArticleDOI
TL;DR: In this article, the reactions of HCOOH and CH3COOH on CeO2(111) and CeO 2(100) were studied using temperature programmed desorption (TPD) and high resolution electron energy loss spectroscopy (HREELS).

TL;DR: In this article, a halogen-free Bronsted acidic deep eutectic solvents (DES) were prepared by mixing new quaternary ammonium methanesulfonate salts with p-toluenesulfonic acid (PTSA).

TL;DR: Using readily accessible 10-sulfonamido-isoborneols as regenerable, chiral auxiliaries, highly face-selective C-C-bond formations at Cα and Cβ of carboxylates could be conveniently achieved.
Abstract: Using readily accessible 10-sulfonamido-isoborneols as regenerable, chiral auxiliaries, highly face-selective C–C-bond formations at Cα and Cβ of carboxylates could be conveniently achieved. Thus, conjugated additions of RCu to enoates (12) furnished, after saponification, β-substituted carboxylic acids 3 in 94–98% e.e. Similarly, propionates 12 yielded after deprotonation, enolate alkylation, and reductive ester cleavage the (R)-alcohols 15 in 78–98% e.e. The acid (+)-3e was converted to the pheromone (–)-11.

TL;DR: In this paper, the synthesis of 1,2,4-oxadiazoles from carboxylic acids and amidoximes using 2-(1 H -benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) was described.

Journal ArticleDOI
TL;DR: In this article, the location of organosulfonic acid groups within mesoporous silica materials was investigated to investigate the acid strength of the resulting solid acid catalyst as a result of acid site cooperativity.
