A porous cross-linked poly(ethyleneamine)-polysulfonamide (PEA-PSA) as a novel organic support system was synthesized in the presence of silica template by nanocasting technique. The paper demonstrated immobilization of CuI nanoparticles inside the pores (PEA-PSA@CuI) for the facile recovery and recycling of these nanoparticles. The presence of porous PEA-PSA and PEA-PSA@CuI nanocomposites was confirmed using FT-IR spectroscopy, FE-SEM, EDX, TGA, XRD, TEM, BET, XPS, WDX, 1H NMR, and ICP-OES techniques. The PEA-PSA@CuI along with Ag(I)/K2S2O8 was implemented as a reusable cooperative catalyst-oxidant system in the decarboxylative cross-coupling of p-toluenesulfonamide with sustituted carboxylic acids in mild condition. Aromatic, secondary and tertiary aliphatic acids underwent high efficient decarboxylative processes with p-toluenesulfonamide to afford the corresponding products. This method provides a practical approach for the flexible synthesis of sulfonamides from the readily affordable substrates. The catalyst was highly reusable and efficient, especially in terms of time and yield of the desired product. This study involved multiple reactions and reactants, such as N-(5-Bromopyridin-2-yl)-4-methylbenzenesulfonamide (cas: 207801-52-3Formula: C12H11BrN2O2S).
N-(5-Bromopyridin-2-yl)-4-methylbenzenesulfonamide (cas: 207801-52-3) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ路mol鈭? in the liquid phase and 140.4 kJ路mol鈭? in the gas phase. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Formula: C12H11BrN2O2S
