(sp3)C–C(sp3) and (sp3)C–H bonds in aryl alkanes by the use of NaNO2/HCl was explored. The method is chemical-oxidant-free, transition-metal-free, uses water as the solvent, and proceeds under mild conditions, making it valuable and attractive to syntheticorganicchemistry.
A benzyne-mediated esterification of carboxylic acids and alcohols under mild conditions has been realized, which is made possible via a selective nucleophilic addition of carboxylic acid to benzyne in the presence of alcohol. After a subsequent transesterification with alcohol, the corresponding esters can be produced efficiently. This benzyne-mediated protocol can be used on the modification of Ibuprofen

We report here a strategy for inert C–C bondfunctionalization. Site-specific cleavage and functionalization of a saturated C(sp3)–C(sp3) bond via a visible-light-induced radical process have been achieved. The general features of this reaction are as follows. (1) Both linear and cyclic C(sp3)–C(sp3) bonds with a vicinal arene can be specifically functionalized. (2) One carbon is converted into a ketone

The present invention relates to phenylacetic acid ester derivatives of the following general formula: ##STR1## wherein, R is selected from the group consisting of lower alkyl (other than ethyl) and substituted lower alkyl, and R' may be a hydrogen or methyl. The compounds obtained by the present invention possess a high degree of analgetic ,antipyretic and anti-inflammatory activites and cause little side effects on the gastro-intestinal tracts, when administered orally and topically, and they may be useful as oral and topical analgetics, antipyretics and antiinflammatory agents.
