Chen, Mao; Buchwald, Stephen L. published an article in 2013, the title of the article was Continuous-flow synthesis of 1-substituted benzotriazoles from chloronitrobenzenes and amines in a C-N bond formation/hydrogenation/diazotization/cyclization sequence.Product Details of 38939-88-7 And the article contains the following content:

We have developed an efficient and regiospecific synthesis of 1-substituted benzotriazoles from chloronitrobenzenes and amines by a C-N bond formation/hydrogenation/diazotization/cyclization sequence under continuous-flow conditions. Two approaches beginning either with an SnAr reaction or Pd catalysis were developed to prepare unsym. substituted benzotriazoles with a range of substituents. Of particular note is that benzotriazoles that bear various N-substituted groups, including alkyl, aryl, and heteroaryl, can all be efficiently and regiospecifically accessed with the described method. This protocol represents a successful example of a continuous-flow method with consecutive multiphase processes. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Product Details of 38939-88-7

Igder, Aghil; Pye, Scott; Mohammed Al-Antaki, Ahmed Hussein; Keshavarz, Alireza; Raston, Colin L.; Nosrati, Ata published an article in 2020, the title of the article was Vortex fluidic mediated synthesis of polysulfone.Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene) And the article contains the following content:

Polysulfone (PSF) was prepared under high shear in a vortex fluidic device (VFD) operating in confined mode, and its properties compared with that prepared using batch processing. This involved reacting the pre-prepared disodium salt of bisphenol A (BPA) with a 4,4′-dihalodiphenylsulfone under anhydrous conditions. SEM (SEM) established that in the thin film microfluidic platform, the PSF particles are sheet-like, for short reaction times, and fibrous for long reaction times, in contrast to spherical like particles for the polymer prepared using the conventional batch synthesis. The operating parameters of the VFD (rotational speed of the glass tube, its tilt angle and temperature) were systematically varied for establishing their effect on the mol. weight (Mw), glass transition temperature (Tg) and decomposition temperature, featuring gel permeation chromatog. (GPC), differential scanning calorimetry (DSC) and thermal gravimetric anal. (TGA) resp. The optimal VFD prepared PSF was obtained at 6000 rpm rotational speed, 45° tilt angle and 160°C, for 1 h of processing with Mw ∼10 000 g mol-1, Tg ∼158°C and decomposition temperature ∼530°C, which is comparable to the conventionally prepared PSF. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene)
