I found the field of Chemistry very interesting. Saw the article Synthesis and characterization of a novel organic-inorganic hybrid salt and its application as a highly effectual Bronsted-Lewis acidic catalyst for the production of N,N ‘-alkylidene bisamides published in 2021. SDS of cas: 99-61-6, Reprint Addresses Zare, A; Sajadikhah, SS (corresponding author), Payame Noor Univ, Dept Chem, POB 19395-3697, Tehran, Iran.. The CAS is 99-61-6. Through research, I have a further understanding and discovery of 3-Nitrobenzaldehyde
In this research, a novel organic-inorganic hybrid salt, namely,N-1,N-1,N-2,N-2-tetramethyl-N-1,N-2-bis(sulfo)ethane-1,2-diaminium tetrachloroferrate ([TMBSED][FeCl4](2)) was prepared and characterized by Fourier-transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDX), elemental mapping, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), thermal gravimetric (TG), differential thermal gravimetric (DTG), and vibrating-sample magnetometry (VSM) analyses. Catalytic activity of the hybrid salt was tested for the synthesis ofN,N ‘-alkylidene bisamides through the reaction of benzamide (2 eq.) and aromatic aldehydes (1 eq.) under solvent-free conditions in which the products were obtained in high yields and short reaction times. The catalyst was superior to many of the reported catalysts in terms of two or more of these factors: the reaction medium and temperature, yield, time, and turnover frequency (TOF). [TMBSED][FeCl4](2)is a Bronsted-Lewis acidic catalyst; there are two SO3H groups (as Bronsted acidic sites) and two tetrachloroferrate anions (as Lewis acidic sites) in its structure. Highly effectiveness of the catalyst for the synthesis ofN,N ‘-alkylidene bisamides can be attributed to synergy of the Bronsted and Lewis acids and also possessing two sites of each acid.
