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 Additive-Free Isomerization of Allylic Alcohols to Ketones with a Cobalt PNP Pincer Catalyst, published in 2019, which mentions a compound: 1086138-36-4, mainly applied to cobalt PNP Pincer complex preparation oxidation potential; allylic alc cobalt catalyst green isomerization; alkanone preparation; allylic alcohols; cobalt catalysts; isomerization; ketones; pincer ligands, Category: benzothiophene.
Catalytic isomerization of allylic alcs. in ethanol as a green solvent was achieved by using air and moisture stable cobalt (II) complexes in the absence of any additives. Under mild conditions, the cobalt PNP pincer complex substituted with Ph groups on the phosphorus atoms appeared to be the most active. High rates were obtained at 120°, even though the addition of one equivalent of base increases the speed of the reaction drastically. Although some evidence was obtained supporting a dehydrogenation-hydrogenation mechanism, it was proved that this is not the major mechanism. Instead, the cobalt hydride complex formed by dehydrogenation of ethanol was capable of double-bond isomerization through alkene insertion-elimination.
In addition to the literature in the link below, there is a lot of literature about this compound(Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine)Category: benzothiophene, illustrating the importance and wide applicability of this compound(1086138-36-4).
