Recent developments and comparison of transformation strategies for organic halides to aldehydes and ketones.

Abstract

Aldehydes and ketones are parts of millions of compounds and are important classes of chemicals which serve as important precursors for the synthesis of library of compounds. For the synthesis of aldehydes and ketones, one impressive approach to date, because of its excellent selectivity, high yield and stability toward over-reduction and over-oxidation, is the oxidation of organic halides (viz. aliphatic and benzyl halides). The current review covers the conventional and eco-friendly transformational approaches, from 2000 to date, toward synthesis of aldehydes and ketones from organic halides, including mechanistic studies, comparison of different transformational strategies and discussion on scope and cons and pros of each transformational approach. The review would be beneficial to get knowledge about recent synthesis techniques, select finest synthetic approach, develop further new transformational methodologies and improve current transformational approaches.
