 ation of Renewable Resources''

\nCette conférence sera prononcée (en anglais) par la Professeu
 re Kyoko Nozaki de l'université de Tokyo.
\nRésumé :Carbon dioxide is
  one of the most attractive renewable C1 resources\, which has many practi
 cal advantages such as abundance\, economic efficiency\, and lack of toxic
 ity. The favorable nature as a carbon source is\, however\, inextricably l
 inked to its inherent inertness. Here we report a new strategy to circumve
 nt thermodynamic and kinetic barriers for copolymerizations of carbon diox
 ide and olefins by using a meta-stable lactone intermediate\, 3-ethylidene
 -6-vinyltetrahydro-2H-pyran-2-one\, which is formed by the palladium-catal
 yzed condensation of carbon dioxide and 1\,3-butadiene. Subsequent free ra
 dical polymerization of the lactone intermediate afforded high-molecular-w
 eight polymers with a carbon dioxide content of 33 mol% (29 wt%). 1
\nOur 
 latest results in direct and selective hydrogenolysis of sp2 C–OH bonds 
 in arenols and O–CH3 bonds in aryl methyl ethers by hydroxycyclopentadie
 nyl dihydridoiridium catalysts will be also presented\, implying their pot
 ential application for mass production of arenes from lignin or its degrad
 ed components.2
