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 Application of palladium (trioxo-adamantyl cage phosphine)chloride complexes as catalysts for the alkoxycarbonylation of styrene; Pd catalysed tert-butoxycarbonylation of styrene, published in 2012, which mentions a compound: 97739-46-3, mainly applied to palladium trioxo adamantyl cage phosphine chloride complex catalysts; alkoxycarbonylation styrene palladium catalyzed tert butoxycarbonylation styrene, SDS of cas: 97739-46-3.
Pre-catalysts of type [PdCl(allyl)(monophosphine)] where the monophosphine is one of the tri-oxo-adamantyl cage phosphines such as 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxo-6-phospha-adamantane give very high reactivity in the regioselective hydroxycarbonylation and alkoxycarbonylation (hydro-esterification) of styrene at 60 °C. This high reactivity enables the use of tert-butanol as nucleophile in the alkoxycarbonylation of styrene.
There are many compounds similar to this compound(97739-46-3)SDS of cas: 97739-46-3. if you want to know more, you can check out my other articles. I hope it will help you,maybe you’ll find some useful information.
