Title:
FORMATION OF ENEDIYNES BY REDUCTIVE COUPLING FOLLOWED BY ALKYNE METATHESIS
Document Type and Number:
WIPO Patent Application WO2004026454
Kind Code:
A3
Abstract:
One aspect of the present invention relates to methods of preparing enedialkylidyne complexes, enediynes, and alkyne metathesis catalysts, as well as methods of catalyzing alkyne metathesis reactions. The present invention also relates to methods of activating enedialkylidyne complexes for metathesis. The present invention also relates to enedialkylidyne complexes.
