《Transition-Metal-, Additive-, and Solvent-Free [3+3] Annulation of RCF2-Imidoyl Sulfoxonium Ylides with Cyclopropenones to Give Multifunctionalized CF3-Pyridones》 was written by Wen, Si; Chen, Yanhui; Tian, Qingyu; Zhang, Yuqing; Cheng, Guolin. Product Details of 1774-47-6This research focused ontriaryl trifluoromethylpyridone preparation green chem; imidoyl sulfoxonium ylide cyclopropenone annulation. The article conveys some information:
An efficient and practical strategy was developed to synthesize 1,3,4-triaryl-6-trifluoromethylpyridones from CF3-imidoyl sulfoxonium ylides and cyclopropenones in good to excellent yields. This stepwise [3+3] annulation reaction was carried out under transition-metal-, additive-, and solvent-free conditions, generating 1 equiv of DMSO as byproduct and tolerating a series of functional groups. The experimental part of the paper was very detailed, including the reaction process of Trimethylsulfoxonium iodide(cas: 1774-47-6Product Details of 1774-47-6)
Trimethylsulfoxonium iodide(cas: 1774-47-6) reacts with sodium hydride to prepare dimethyloxosulfonium methylide, which is used as a methylene-transfer reagent in synthetic chemistry. It is used to prepare ylide, which reacts with carbonyl compounds to get epoxides. Further, it reacts with alfa,beta-unsaturated esters to get cyclopropyl esters.Product Details of 1774-47-6
