Metal-Free Dehydrogenation of N-Heterocycles by Ternary h-BCN Nanosheets with Visible Light

An efficient metal-free catalytic system has been developed based on hexagonal boron carbon nitride (h-BCN) nanosheets for the dehydrogenation of N-heterocycles with visible light; hydrogen gas is released in the process, and thus no proton acceptor is needed. This acceptorless dehydrogenation of hydroquinolines, hydroisoquinolines, and indolines to the corresponding aromatic N-heterocycles occurred in excellent yield under visible-light irradiation at ambient temperature. With h-BCN as the photocatalyst and water as the solvent, this environmentally benign protocol shows broad substitution tolerance and high efficiency.

, p. 604 - 605 (1982)
The new alkaloid komarovinine has been isolated from the total ether-extracted alkaloids of the epigeal part of Nitraria komarovii.It has also been found among the products of the dehydrogenation of nitrarine by selenium and sulfur.On the basis of the available facts, the structure of one of the isomers of 1-quinolinyl-β-carboline was proposed for komarovinine.A direct comparison with synthetic samples shows the identity of the alkaloid to 1-(quinolin-6'-yl)-β-carboline. 1-(Quinolin-7'-yl)-β-carboline, not previously described in the literature, has been characterized.

Remarkable effect of nitrogen dioxide for N-hydroxyphthalimide-catalyzed aerobic oxidation of methylquinolines
Sakaguchi, Satoshi,Shibamoto, Akihiro,Ishii, Yasutaka
, p. 180 - 181 (2007/10/03)
Aerobic oxidation of methylquinolines was successfully achieved by the use of N-hydroxyphthalimide/Co(OAc)2/Mn(OAc)2 as catalyst in the presence of a small amount of nitrogen dioxide as an initiator.
