Direct ortho-C–H Functionalization of Aromatic Alcohols Masked by Acetone Oxime Ether via exo-Palladacycle
摘要:
Use of an iridium catalyst allowed the efficient dehydrogenative functionalization of C-H bonds of azulenes with the production of hydrogen as the sole byproduct. The reaction occurred with excellent chemo- and regioselectivities to provide 2-silylazulenes even without any directing groups. Effective conjugation through the 2-position of the azulene ring was demonstrated by the unique stimuli-responsiveness against an acidbase reaction.
