Popis: Hydrido (phosphonite) cobalt(I) [CoH{PPh(OEt)_2}_4], (CoHL_4) (L=PPh(OEt)_2) under Pyrex-filtered photoirradiation catalyzed dehydrogenation reaction of 2-propanol in the liquid phase, with release of acetone. The turn-over number evaluated for the dehydrogenation for 1h at 82℃ was 4.6, and the quantum yields for the reaction at 366nm were determined to be about 0.015 at 60 and 82℃. The dehydrogenation was characterized as a photoassisted-type catalytic reaction, and the photogenerated hydrido transient CoHL_3 was attributed to a key-role-playing intermediate in the catalytic cycle of the dehydrogenation.
