Quinoline and 4-methylquinoline are alkylated with alkanecarboxylic acid upon visible light- or gamma-irradiation. In the photo-alkylation, iron(III) sulfate not only accelerates the reaction, but also improves the selectivity for alkylation. Titanium oxide shows smaller effects than iron(III) sulfate.

Quinoline and 4-methylquinoline are efficiently alkylated with alkanoic acid in the presence of iron(III) sulfate upon visible light-irradiation. Iron(III) sulfate not only accelerates the photoreaction but also increases the yield of alkylation. Gamma-irradiation also brings about the alkylation. In the photo- and radiation-induced alkylation with alkanoic acid, alkyl radicals play important roles.
We proposed a Minisci-type strategy for the alkylation of heterocycles with a variety of boron species under low cost and easily scale-up conditions without the use of transition-metal or organo-catalysts. The extension of this strategy to other systems will provide green approaches for the post-modifications of drug molecules and complex natural products.

Provided are novel organic electroluminescent compounds and organic electroluminescent devices using the same. Since the organic electroluminescent compound exhibits good luminous efficiency and excellent life property compared to the existing material, it may be used to manufacture OLED devices having superior operation life and consuming less power due to improved power efficiency.
