, p. 76 - 80 (1995)
The ground-state conformation and fluorescence properties of two closely related dyes 2-(2'-hydroxyphenyl)imidazopyridine (1,2-HPIP) and 3-(2'-hydroxyphenyl)imidazopyridine (1,5-HPIP) have been studied in various solvents at room temperature

A new convenient route for the synthesis of 3-substituted-imidazo[1,5-a]pyridines has been described as well as the scope and limitations of the method are evaluated. By reacting 2-picolylamine and different aldehydes in presence of selenium dioxide as the oxidant, a series of 3-substituted imidazo[1,5-a]pyridines was isolated in good yields. Different kinds of aldehydes such as aliphatic, aromatic, heterocyclic as well as aromatic ring carrying some substituents have been used.

3-Aryl-1-phosphinoimidazo[1,5-a]pyridine ligands were synthesized from 2-aminomethylpyridine as the initial substrateviatwo complementary routes. The first synthetic pathway underwent the coupling of 2-aminomethylpyridine with substituted benzoyl chlorides, followed by cyclization, iodination and palladium-catalyzed cross-coupling phosphination reactions sequence to give our phosphorus ligands. In the second route, 2-aminomethylpyridine was cyclized with aryl aldehydes, followed by the iodination and palladium-catalyzed cross-coupling phosphination reactions to yield our phosphorus ligands. The 3-aryl-1-phosphinoimidazo[1,5-a]pyridine ligands were evaluated in palladium-catalyzed sterically-hindered biaryl and heterobiaryl Suzuki-Miyaura cross-coupling reactions.

The direct sequential arylation reaction at the C3 and C1 positions of imidazo[1,5-a]pyridines with a variety of aryl iodides catalyzed by [Pd(phen)2](PF6)2 is described. The reaction of unsubstituted imidazo[1,5-a]pyridine with various aryl iodides proceeded selectively at the C3 position to exclusively give the corresponding C3-arylated products. The one-pot double-arylation reaction at the C3 and C1 positions of unsubstituted imidazo[1,5-a]pyridine with different aryl groups was also achieved.

experimental part, p. 284 - 286 (2010/03/26)
3-Substituted-imidazo[1,5-a]pyridines were conveniently synthesized in two steps from commercially available picolinic esters under microwave irradiation conditions.
