promoter of the [1,2]-Wittig rearrangement of aryl benzyl ethers and thus allow the two-step synthesis of isomerically pure substituted diarylmethanols starting from simple hydroxybenzoic acid derivatives. The method is compatible with a wide range of functional groups including methyl, methoxy, and fluoro, although not with nitro and, unexpectedly, is applicable to meta as well as ortho and para isomeric

An environmentally friendly synthetic route by the application of CO2 to synthesize amides via in situ protection and deprotection of amines for iron catalyzed oxidative amidation of aldehydes was developed. Various secondary and tertiary amides have been synthesized in moderate to good yields under mild and neutral reaction conditions. The use of amine hydrochloride salts and hence base for neutralization step is totally avoided in this protocol. (C) 2015 Elsevier Ltd. All rights reserved.
