In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Facile preparation of the water-soluble singlet oxygen traps anthracene-9,10-divinylsulfonate (AVS) and anthracene-9,10-diethylsulfonate (AES) via a Heck reaction with vinylsulfonate, published in 2005-10-17, which mentions a compound: 172418-32-5, mainly applied to anthracene Heck reaction divinylsulfonate palladium catalyst; divinylsulfonate anthracene preparation reduction rate constant; singlet oxygen reaction anthracene divinylsulfonate; endoperoxide anthracene divinylsulfonate preparation; diethylsulfonate anthracene preparation rate constant, Category: chiral-phosphine-ligands.
An easy 2-step method for the synthesis of the water-soluble singlet oxygen trap AES was developed. The method is based on a novel Heck reaction with sodium vinylsulfonate followed by vinyl hydrogenation. It is shown that the Heck product AVS is also suitable as a water-soluble and colored singlet oxygen trap that allows singlet oxygen to be detected specifically and simply by visual inspection. The cumulative amount of 1O2 generated into the solution can be determined unambiguously by measuring the concentration of the endoperoxides AVSO2 or AESO2 by HPLC or by 1H NMR.
I hope my short article helps more people learn about this compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium)Category: chiral-phosphine-ligands. Apart from the compound(172418-32-5), you can read my other articles to know other related compounds.
