An efficient alkylsulfonate functionalized metal organic framework (MOF), MIL-101-Cr-NH-RSO3H, has been successfully synthesized through a post-synthetic modification strategy of MIL-101-Cr-NH2 with 1,3-propanesultone reagent. The high surface area of the MIL-101-Cr-NH2 MOF guaranteed the high dispersion of -SO3H active species and the large pore size improved the contacting ability between the substrate and these active sites. The solid MIL-101-Cr-NH-RSO3H catalyst exhibited high catalytic performance in the preparation of quinoxaline derivatives by the condensation of benzene-1,2-diamines with 1,2-dicarbonyl compounds. Furthermore, the MIL-101-Cr-NH-RSO3H catalyst exhibits good stability, general applicability and excellent recycling performance.

In an effort to diminish the cost of perovskite solar cells (PSCs) with regard to hole transport materials (HTMs), we employed an easily attainable condensation route to synthesize a cheap and efficient HTM. Using a newly engineered small organic molecule

Here, the hydrothermal synthesis (HTS) of 2,3-diarylquinoxalines from 1,2-diketones and o-phenylendiamines (o-PDAs) was achieved. The synthesis is simple, fast, and generates high yields, without requiring any organic solvents, strong acids or toxic catalysts. Reaction times down to 90 % in all cases). Moreover, it was shown that HTS has high compatibility: (i) hydrochlorides, a standard commercial form of amines, could be used directly as combined amine source and acidic catalyst, and (ii) Boc-diprotected o-PDA could be directly employed as substrate that underwent HT deprotection. A systematic large-scale computational comparison of all reported syntheses of the presented quinoxalines from the same starting compounds showed that this method is more environmentally friendly and less toxic than all existing methods and revealed generic synthetic routes for improving reaction yields. Finally, the application of the synthesized compounds as fluorescent dyes for cell staining was explored.

An efficient, simple and eco-friendly procedure is reported in presence of heterogeneous Dowex 50W catalyst in aqueous medium under refluxing condition to produce quinoxaline derivatives. Catalyst has participated in condensation reaction between 1,2-diamines and various aromatic 1,2-diketones smoothly with excellent yield of the products in short reaction times. Dowex 50W was used more than five times in this reaction separately and showed an excellent recyclability throughout the reaction.(figure presented).
