标题:无金属条件下可见光介导的二噻吩脱保护
摘要:开发了在无金属条件下可见光介导的简便和选择性二噻吩脱保护的方法.曙红y(1Mol%)被证明是在环境光氧化还原条件下对二噻吩脱保护的有效催化剂.事实证明,标准的家用紧凑型荧光灯光源(cfl灯泡)在露天条件下于室温在乙腈水溶液中有效.表现出较宽的底物范围和官能团耐受性的方案已显示出可扩展至富电子和缺陷型硫缩醛和硫缩酮的转化范围.该协议的综合效用也已通过克规模的应用得到了证明.

标 题:Process for producing diphenylethers and esters
发明人：LOURENS GERHARDUS JOHANNES
权利人:DOW CHEMICAL CO
摘要:An improved synthesis of diphenylethers, and in particular, the bacteriostat 2,4,4'-trichloro-2'-hydroxydiphenylether, is described wherein 2'-acetyl-2,4,4'-trichlorodiphenylether is oxidised under Baeyer-Villiger conditions to produce 2'-acetoxy-2,4,4'-trichlorodiphenylether in near quantitative yield. Best oxidative conditions include the use of anhydrous permaleic acid produced in situ. The ester is purified readily by simple recrystallization, as no dibenzofurans and only minor amounts of byproducts are formed in the process. The ester is converted into the desired halogenated phenolic diphenylether, 2,4,4'-trichloro-2'-hydroxydiphenylether, by hydrolysis or transesterification. The final product is purified to a high degree by vacuum distillation and crystallization to meet current purity standards for approved applications.
