A novel rhenium complex bearing a non-innocent PNP pincer ligand was prepared. This novel catalyst is active in hydrogen autotransfer reactions to form new C-C and C-N bonds. More specifically, valuable alkylations of ketones and sulfonamides with primary alcohols are herein presented. In addition, the first examples of rhenium-catalysed synthesis of pyrroles are described by dehydrogenative coupling of diols, amines and ketones.
制备了一种带有非惰性PNP钳形配体的新型铼配合物。这种新型催化剂在氢自转移反应中具有活性，可形成新的C-C键和C-N键。更具体地说，本文展示了酮和磺酰胺与伯醇的有价值的烷基化反应。此外，通过二醇、胺和酮的脱氢偶联描述了铼催化合成吡咯的首例反应。
