complex: Milstein's complex, (PNN)RuHCl(CO), catalyzes the efficient reduction of alkyl bromides and chlorides under relatively mild reaction conditions by using propan-2-ol and a base. Sterically hindered tertiary and neopentyl substrates are reduced efficiently, as well as more-functionalized aryl and alkyl bromides. The reaction appears to occur by a radical pathway, and provides an alternative to
一个简单的配合物:米尔斯坦配合物(PNN)RuHCl(CO),通过使用丙-2-醇和一种碱,在相对温和的反应条件下催化有效还原烷基溴化物和氯化物。受阻位的叔和新戊基底物以及功能更强的芳基和烷基溴化物均能有效还原。该反应似乎是通过自由基途径发生的,它提供了硅烷,氢化锂铝和锡基还原的替代方法。
