摘要

二氨基环戊二烯酮钌络合物可以通过选择添加剂来控制钌催化丙炔醇异构化反应的区域选择性。因此，迈耶-舒斯特重排产物和氧化还原异构化产物都可以选择性地获得。在羟胺-O-磺酸存在的情况下，则会形成不饱和腈。钌催化剂易于获得，并且对水分、空气和酸性条件稳定。

Regiocontrolled Ruthenium-Catalyzed Isomerization of Propargyl Alcohols

A diaminocyclopentadienone ruthenium complex allows control of regioselectivity in the ruthenium-catalyzed isomerization of propargyl alcohols through the choice of additive. Thereby, both products of the Meyer–Schuster rearrangement and redox isomerization products are selectively accessible. In the presence of hydroxylamine-O-sulfonic acid, unsaturated nitriles are formed instead. The ruthenium catalyst is readily available and stable to moisture, air, and acidic conditions.
