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

Synthesis of chiral cyclohexanes and carbasugars by 6-exo-dig radical cyclisation reactions
Treatment of 5-(tert-butyldimethylsilyl)-2,3-O-isopropylidene-D-ribose with lithium acetylides gave mixtures of syn- and anti-alkynols 2a–2c which were separated following protection as methoxymethyl ethers.
