β¦ Synopsis
Alkyl, vinyl and aryl substituted carbazoles at the 3-and 6-positions are prepared in high yield from the corresponding 3,6-dibmmocarbazole via nickel catalyzed coupling with Grignard reagents (Corriu-Kumada coupling).

## Abstract A systematic study on the __Stille__ and __Sonogashira__ crossβcoupling of iodinated imidazo[1,2β__a__]pyridines was performed, permitting the preparation of various vinylβ, ethynylβ, and allenylβsubstituted derivatives. These methods are particularly valuable, given their experimental
The palladium-catalyzed homobenzyl-aryl, horobenzyl-alkenyl, homoallyl-aryl, and homopropargyl-aryl cross coupling reactlons provide the desired coupling products in high yields,
