Recently I am researching about ONE-POT SYNTHESIS; SULFUR-DIOXIDE; ARYLSULFONYL CHLORIDES; BORONIC ACIDS; NITROARENES; DABSO; 3-COMPONENT; SULFONES; HALIDES; ARYL, Saw an article supported by the National Natural Science Foundation (NSF) of ChinaNational Natural Science Foundation of China (NSFC) [21572203, 21472140]; NSF of Zhejiang ProvinceNatural Science Foundation of Zhejiang Province [LZ16B020001]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Chen, K; Chen, W; Han, B; Chen, WZ; Liu, MC; Wu, HY. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid. HPLC of Formula: C7H5NO4
A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.
HPLC of Formula: C7H5NO4. Welcome to talk about 62-23-7, If you have any questions, you can contact Chen, K; Chen, W; Han, B; Chen, WZ; Liu, MC; Wu, HY or send Email.
