Sonogashira cross-coupling reactions of 3,5-dibromo-2,6-dichloropyridine

A new method for the chemoselective synthesis of alkynylpyridines from 3,5-dibromo-2,6-dichloropyridine has been developed. Optimized conditions give access to a variety of mono-, di-, tri- and tetraalkynylated pyridines in good yields. Interestingly, the employment of 3,5-dibromo-2,6-dichloropyridine as a starting material led to the opposite regioisomers of dialkynylated pyridines as compared to the application of 2,3,5,6-tetrachloropyridine.

Synthesisandpropertiesof5,7-Dihydropyrido[3,2-b:5,6-b′]diindoles

5,7-Dihydropyrido[3,2-b:5,6-b]diindoles were prepared by a highly efficient two-step synthesis that involved a site-selective Suzuki coupling reaction of 2,3,5,6-etrabromopyridine and a subsequent Pd-catalyzed cyclization that proceeded through a twofold C-N coupling reaction with aromatic and aliphatic amines. With the exception of the parent molecule, which was described in a patent without any characterization data, the 5,7-dihydropyrido[3,2-b:5,6-b]diindoles are a new chemical entity. Their electrochemical and photochemical properties were investigated. These pyridodiindoles show promising fluorescence properties with good quantum yields and interesting electrochemical behavior. The optical and electronical properties were analyzed and explained by using DFT calculations.

A Convenient Synthesis of 2,3,5,6-Tetrahalogenopyridines and of 3,5-Bis(alkylthio)pyridines from 2,6-Diaminopyridine

Controlled chlorination of 2,6-diaminopyridine (1) affords 2,6-diamino-3,5-dichloropyridine (2a) which is then bis(diazotised) to give 2,3,5,6-tetrachloropyridine (3a); similarly prepared are other 2,3,5,6-tetra(chloro/bromo) pyridines and 2,6-dichloro-3,5-bis(thiocyanato)pyridine (3h), from which 3,5-bis(alkylthio)pyridines are easily obtained.
