标题:Cds Sheet-rgo纳米复合材料上可见光驱动的有机叠氮化物对胺的光催化有效还原
摘要:Cds Sheet-Rgo纳米复合材料作为非均相光催化剂,可以使用水合肼作为还原剂,将可见光诱导的芳族,杂芳族,脂族和磺酰基叠氮化物光催化还原为相应的胺.该反应在没有自光活化偶氮化合物的情况下,对胺的形成显示出优异的转化率和化学选择性.在所采用的策略中,Cds不仅通过叠氮化物的光活化促进了亚硝基的形成,而且在一定程度上增强了叠氮化物的分解,从而完全抑制了偶氮化合物的形成.开发的cds Sheet-Rgo纳米复合催化剂非常活泼,在用40 W简易家用cfl灯照射下可提供出色的结果.

发明人：DESBOIS MICHEL
权利人:RHONE POULENC SPEC CHIM
摘要:A process for the preparation of alpha , alpha -difluoroalkoxy or alpha , alpha -difluoroalkylthiophenyl sulfones, in which a polyhaloalkoxybenzene or a polyhaloalkylthiobenzene is reacted with a sulfonic acid, a derivative or a precursor of this acid, in the presence of boron trifluoride in an amount such that the absolute pressure of the boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent. The resultant products are useful as intermediates in the synthesis of compounds having a phytosanitary (e.g., herbicidal) or pharmaceutical activity.
