Deprotometalation-Iodolysis and Direct Iodination of 1-Arylated 7-Azaindoles: Reactivity Studies and Molecule Properties

Molecules, 2021
Five protocols were first compared for the copper-catalyzed C-N bond formation between 7-azaindole and aryl/heteroaryl iodides/bromides. The 1-arylated 7-azaindoles thus obtained were subjected to deprotometalation-iodolysis sequences using lithium 2,2,6,

Capture of organic iodides from nuclear waste by metal-organic framework-based molecular traps

Nature Communications, 2017
Capturing radioactive organic iodides from nuclear waste is important for safe nuclear energy usage, but remains a significant challenge. Here, Li and co-workers fabricate a stable metal–organic framework functionalized with tertiary amine groups that ...

Nickel-catalyzed carbonylative synthesis of dihydrobenzofurans

Catalysis Communications, 2021
A nickel-catalyzed carbonylative synthesis of dihydrobenzofurans has been developed. With Mo(CO)6 as the CO source and manganese metal as the reductant, alkyl halides were reacted with aryl iodides to give the desired products in moderate to good yields.

SYNTHESIS OF SOME NEW IMIDAZOLIUM AND PURINIUM SALTS AND THEIR RELATED DERIVATIVES

Zagazig Journal of Pharmaceutical Sciences, 1997
Cyclization of 5-amino-1-(4-methoxyphenyl) imidazole-4-carbonitrile 3 with formamide afforded 6-aminopurine derivative 4. When the latter was reacted with alkyl iodides, the purinium iodide salts 7a-c were obtained.
