What is the functional group of an ester?Functional Group:There are some of the functional group that looks similar like -COOH group, CHO group,-COOR group, C=O group but have different -different chemical properties. Therefore the properties of the organic compound gets affected by the group...
Date Dec. 14, 1989.The present invention relates to compounds comprising ester groups having at least three ester functions, to processes for the production thereof, and to the use of the products. Compounds having at least three functional ester groups of the general formula: ...

Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter sol
摘要: A process for continuously preparing a compound which bears at least two functional groups which are each independently selected from the group consisting of nitrile group, carboxylic acid group, carboxylic ester group and carboxamide group....
The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides Ester Esters have a pair of alkyl or aromatic groups attached to a carbonyl + linking oxy...
The two main functional groups that affect the soil-water system are: (a) groups having a C–O bond, for example, carboxyl, carbonyl, hydroxyl, methoxyl, and ester groups and (b) the nitrogen-bonding functional groups, for example, amine and nitrile groups. For example, depending on how ...

In these conditions, a [3, 3] sigmatropic rearrangement after reaction with triethyl orthoacetate gives rise to an ester functional group, attached to the graphitic framework via a robust CC bond. This variation of the Claisen rearrangement offers an unprecedented versatility of further ...
