Abstract
:: An efficient direct oxidation method was developed to oxidize some aromatic and aliphatic aldehydes to esters by the dual utilization of NaIO4 and Pd-C. At ambient conditions, various aldehydes were employed in a clean esterification reaction to afford numerous esters in good to excellent yields. By this adopted method, some multifunctional aldehydes, high-energy-containing aromatic and unsaturated aldehydes, were advantageously oxidized to esters without noticeable difficulties. Moreover, no over-oxidation occurred to alcohols, and most byproducts were not formed during this oxidation process. Conventional and some modern methods lag behind owing to their easier operability and easy work-up process. This investigation has proven that the required oxidant (NaIO4) or catalyst (Pd-C) is useless to employ in excess, although some current methods utilize hugely expensive reagents for such conversions. Mundane reaction set-up, easy product recovery technique, non-toxic catalyst, and cheap and available starting materials are the noteworthy advantages of this method.
期刊介绍:
Current Organic Chemistry aims to provide in-depth/mini reviews on the current progress in various fields related to organic chemistry including bioorganic chemistry, organo-metallic chemistry, asymmetric synthesis, heterocyclic chemistry, natural product chemistry, catalytic and green chemistry, suitable aspects of medicinal chemistry and polymer chemistry, as well as analytical methods in organic chemistry. The frontier reviews provide the current state of knowledge in these fields and are written by chosen experts who are internationally known for their eminent research contributions. The Journal also accepts high quality research papers focusing on hot topics, highlights and letters besides thematic issues in these fields. Current Organic Chemistry should prove to be of great interest to organic chemists in academia and industry, who wish to keep abreast with recent developments in key fields of organic chemistry.
