Our investigation of this cross-electrophile coupling began with the reaction of 4-methyl-benzoic acid (1) with 5-bromo-2-(trifluoromethyl) pyridine (2), and the representative results are presented in Table 1. The optimized reaction conditions include 2 mol% [Ir{dF(CF3)ppy}2{dtbbpy}]PF6...
Finally, selective epoxidation of the unconjugated olefin in nordeoxyelephantopin 1b using meta-chloroperbenzoic acid (mCPBA) afforded the norelephantopin 3b. It is noteworthy that only Grubbs I is competent to form the desired cyclisation product; under otherwise identical conditions, Grubbs II ...

4-Piperidinecarboxylic acid was purchased from Merck (Germany). AR grade solvents of Merck (methanol), Lab-scan (DMSO), and Riedel-de Haen (petroleum ether) origin were used. The solvents were dried before use by standard procedures [18]. The samples were taken in capillary tubes and ...
There is also substrate selectivity; e.g., the isomeric product 2,6-dihydroxy benzoic acid exhibits lower decarboxylation rates [19]. Thus, the use of different phenolic substrates provides different reaction scenarios with different rates of substitution relative to decarboxylation. Accordingly, substrat...
presented that the UiO-67 was prepared using benzoic acid and hydrochloric acid as the regulator under the microwave irradiation, which shortened the reaction time to 2–2.5 h (Vakili et al., 2018). Zhang et al., 2020a, Zhang et al., 2020b stated that the UiO-67/CdS composites were...
With a sufficient amount of precursor7in hand, we then focused our attention on the exploration of the designed intramolecular Robinson annulation. Initially, different secondary amine catalysts were screened to catalyze the desired reaction of7by using benzoic acid (A1) as an additive in dichlorometh...
The chemical synthesis of the TFMO containing amides started by coupling the commercially available 3- or 4-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)benzoic acid (1 or 2) with benzylamine in the presence of equivalent amount of 1-[Bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b...
