Transformation of Metal-Organic Frameworks into Stable Organic Frameworks with Inherited Skeletons and Catalytic Properties
Chen, Kai,Wu, Chuan-De
, p. 8119 - 8123 (2019)
Metal-organic frameworks (MOFs) are an emerging class of porous materials with attractive properties, however, their practical applications are heavily hindered by their fragile nature. We report herein an effective strategy to transform fragile coordinat
Copper corrole catalyzed esterification of C(sp3)-H with carboxylic acids via cross-dehydrogenative coupling reaction

, p. 860 - 870 (2021/05/19)
Copper corrole complex was firstly used as catalyst for oxidative esterification of un-reactive C(sp3)-H bond of cyclic ether and carboxylic acid via cross-dehydrogenative coupling (CDC) reaction using di-tert-butyl peroxide (DTBP) as oxidant.
Microwave-Enhanced Coupling of Carboxylic Acids with Liquid Ketones and Cyclic Ethers Using Tetrabutylammonium Iodide/ t-Butyl Hydroperoxide
Macías-Benítez, Pablo,Moreno-Dorado, F. Javier,Guerra, Francisco M.
, p. 6027 - 6043 (2020/05/22)
The oxidative coupling of carboxylic acids with liquid ketones and cyclic ethers has been accomplished in minutes using t-butyl hydroperoxide in the presence of tetrabutylammonium iodide under microwave irradiation in the absence of a solvent. In addition to drastically shortening the reaction times, the use of microwaves resulted, in general, in yields equal to or higher than those obtained by conventional heating.

The crystal structure of 5,10,15,20-tetra(ethoxycarbonyl)porphyrin copper(ii) showed that its central copper has a six-coordinate structure. An efficient copper porphyrin-catalyzed cross-dehydrogenative coupling (CDC) esterification reaction between C(sp
Iron porphyrin-catalyzed C(SP3) -H activation for the formation of C–O bond via cross-dehydrogenative coupling of cycloether and aromatic acid

, p. 7169 - 7176 (2017/11/17)
An efficient cyclic ether benzoxylation was achieved by using iron porphyrin as the catalyst and di-tert-butyl peroxide oxidant. The benzoic acid substrates bearing electron donating or withdrawing groups could react with cyclic ether smoothly to afford t
Generation of bis-Acyl ketals from esters and benzyl amines under oxidative conditions
Majji, Ganesh,Rajamanickam, Suresh,Khatun, Nilufa,Santra, Sourav Kumar,Patel, Bhisma K.
, p. 3440 - 3446 (2015/04/14)
Treatment of benzylamines with esters at an elevated temperature are expected to give amides. However, in the presence of TBAI/TBHP, esters possessing a methylene carbon α-to oxygen with benzylamines provide bis-esters rather than the expected amides. Benzylamines under oxidative conditions generate less nucleophilic carboxylates, which couples at the sp3 C-H bonds of esters and cyclic ethers to give bis-acyl ketals and α-acyloxy ethers, respectively.
A NCS mediated oxidative C-H bond functionalization: Direct esterification between a C(sp3)-H bond and carboxylic acids

A transition metal free oxidative C-H bond functionalization/esterification of α-alkoxy alkanes with acids is described in this report. This method is effectively mediated by NCS instead of traditional oxidants, like TBHP or its derivatives, and directly
