Azobenzene-bearing
photoswitchable ruthenium catalysts were developed
for olefin metathesis reactions. These catalysts exhibited an on–off
switching ability in ring-closing metathesis depending on UV irradiation
(>99% conversion without UV vs <1% with UV). Photoswitching
phenomena
have been observed in various types of olefin metathesis reactions,
such as ring-opening metathesis, cross-metathesis, and ethenolysis.
The photoswitching feature is also reversible, as the ring-closing
metathesis reaction can repeatedly be turned on and off by switching
the UV light source. Photoisomerization of azobenzene-bearing cyclic(alkyl)(amino)carbene
(azo-CAAC) ligands and the corresponding ruthenium catalysts was observed
by UV–vis spectroscopy.
