Bookmark or Share- Occurrence, distribution, and sources of organophosphate esters (OPEs ...Organophosphate esters (OPEs) are a class of emerging and ubiquitous contaminants that are attracting increasing attention, and their large-scale use as flame retardants and plasticizers has led to their pervasive presence in the environment, although their broader impacts remain unknown. In this st …
- Pd‐Catalyzed Dienylation of Propargylic Esters Enabling Highly ...The stereochemical synthesis of highly substituted Danishefsky-type dienes remains unsolved in organic chemistry. We describe a simple and efficient approach for the stereoselective synthesis of Danishefsky-type trisubstituted dienes from readily available propargylic esters via Pd-catalyzed dienylation reaction through the key intermediate metallacyclobutene in a regio-, chemo- and ...
- Ester - WikipediaIn chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group ( −OH) of that acid is replaced by an organyl group ( −R ). Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well. [1] .

- Ester | Description, Types, & Reactions | Britannicaester, any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common. The term ester was introduced in the first half of the 19th century by German chemist Leopold Gmelin.
