Usage

General Description

1,4-Benzenedicarboxylic acid dihexyl ester, also known as dihexyl phthalate, is a colorless and odorless organic compound commonly used as a plasticizer in PVC products, including vinyl flooring, synthetic leathers, and food packaging materials. It is also found in some personal care products, such as cosmetics and lotions, to improve their texture and consistency. While dihexyl phthalate is considered to have low acute toxicity, there are concerns about its potential long-term health effects, including reproductive and developmental toxicity. As a result, there has been increasing regulatory scrutiny and efforts to reduce its usage in consumer products.

Cesium Carbonate Catalyzed Esterification of N-Benzyl- N-Boc-amides under Ambient Conditions

We report a general activated amide to ester transformation catalyzed by Cs2CO3. Using this approach, esterification proceeds under relatively mild conditions and without the need for a transition metal catalyst. This method exhibits broad substrate scope and represents a practical alternative to existing esterification strategies. The synthetic utility of this protocol is demonstrated via the facile synthesis of crown ether derivatives and the late-stage modification of a representative natural product and several sugars in reasonable yields.

Unsymmetrical dicarboxylic esters as bleach precursors

A bleach precursor compound, its peroxygen derivative, and detergent compositions containing these materials are disclosed herein. The bleach precursors structurally comprise a pair of different diesters, one ester containing an electrically-charged functional group. Perhydrolysis of the precursor in the presence of hydrogen peroxide and a basic aqueous media generates a peroxycarboxylic acid.
