Abstract
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.
期刊介绍：
SYNLETT is an international journal reporting research results and current trends in chemical synthesis in short personalized reviews and preliminary communications. It covers all fields of scientific endeavor that involve organic synthesis, including catalysis, organometallic, medicinal, biological, and photochemistry, but also related disciplines and offers the possibility to publish scientific primary data.
