Abstract Different solid superacid sulfated ZrO 2 (SO 4 2- /ZrO ) samples were successfully prepared by conventional and ultrasonic assisted chemical precipitation process, then they characterized XRD, FT-IR, TGA, BET, NH 3 -TPD Py-FT-IR. The results indicate that the acidity surface area of sample can be increased using ultrasonic. Furthermore, this ultrasonic-assisted catalyst was used for chlorobenzene nitration NO as nitrating agent. shows excellent catalytic activity reusability giving high para selectivity. reaction mechanism proposed combination experimental theoretical calculations. present work provides an easy-to-implement, mild environmentally friendly approach efficient preparation valuable -nitrochlorobenzene, which has extensive industrial application prospects.

In this article, we provide an extended substrate scope and more detailed mechanistic studies of operationally simple generally applicable arene nitration that previously reported. This method utilizes safe inexpensive Fe(NO3)3•9H2O as the nitro source in easily recyclable HFIP obviates need for corrosive acids (HNO3 + H2SO4). As a result, speculated it could serve effective substitute traditional mixed acid approach under most scenarios due to its operational simplicity. A general guidance application was provided.

In this work, we developed a facile and controllable electrophilic aromatic nitration method with commercially available 68% HNO3 as the nitrating reagent trifluoromethanesulfonic acid (HOTf) catalyst in hexafluoroisopropanol or under solvent-free conditions. The products of different arenes can be obtained almost quantitative yields by tuning loading HOTf. strong acidity water absorbing property HOTf allowed transformation to reach completion short time at room temperature.

Abstract A tert ‐butyl nitrite (TBN) promoted visible‐light‐induced one‐pot C−N cross coupling reaction of 3‐alkylidene‐2‐oxindoles with benzene‐1,2‐diamine was explored. Simultaneously, the indoline motif as well 3‐ylidene oxindoles are regioselectively nitrated at C‐6 position by in‐situ formed NO 2 radical. ( E )‐3‐(2‐(aryl)‐2‐oxoethylidene)oxindole and )‐3‐ylidene oxindole produce distinct diastereomeric products, a phenomenon influenced steric bulk functional group. The experimental findings suggest potential involvement radical pathway in this reaction.
