We report the FeCl 3-catalyzed alkylation of nonactivated C(sp 3)-H bonds. Photoinduced ligand-to-metal charge transfer at the iron center generates chlorine radicals that then preferentially abstract hydrogen atoms from electron-ric

The retro-Claisen reaction is frequently used in organic synthesis to access ester derivatives from 1,3-dicarbonyl precursors. The C-C bond cleavage in this reaction is usually promoted by a number of transition-metal Lewis acid catalysts or organic Br?nsted acids/bases. Herein we report a new convenient and efficient method utilizing the tropylium ion as a mild and environmentally friendly organocatalyst to mediate retro-Claisen-type reactions. Using this method, a range of synthetically valuable substances can be accessed via solvolysis of 1,3-dicarbonyl compounds.
Copper-catalyzed remote sp3 C-H chlorination of alkyl hydroperoxides
Kundu, Rituparna,Ball, Zachary T.
supporting information; experimental part, p. 2460 - 2463 (2010/07/05)
A copper-catalyzed methodology to functionalize remote sp3 C-H bonds in alkyl hydroperoxides is presented. The atom-transfer chlorination utilizes simple ammonium chloride salts as the chlorine source, and the internal redox process requires no external redox reagents.
