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 Carboxylation of Aryl Triflates with CO2 Merging Palladium and Visible-Light-Photoredox Catalysts, published in 2019-06-21, which mentions a compound: 676525-77-2, mainly applied to aryl triflate carbon dioxide carboxylation iridium palladium visible light; arylcarboxylic acid preparation; iridium palladium carboxylation catalyst; visible light carboxylation promoter, Name: [Ir(dtbbpy)(ppy)2]PF6.
A visible-light-promoted, highly practical carboxylation of readily accessible aryl triflates at ambient temperature and a balloon pressure of CO2 by the combined use of palladium and photoredox Ir(III) catalysts, is reported. Strikingly, the stoichiometric metallic reductant is replaced by a nonmetallic amine reductant providing an environmentally benign carboxylation process. In addition, one-pot synthesis of a carboxylic acid directly from phenol and modification of estrone and concise synthesis of pharmaceutical drugs adapalene and bexarotene have been accomplished via late-stage carboxylation reaction. Furthermore, a parallel decarboxylation-carboxylation reaction has been demonstrated in an H-type closed vessel that is an interesting concept for the strategic sector. Spectroscopic and spectroelectrochem. studies indicated electron transfer from the Ir(III)/DIPEA combination to generate aryl carboxylate and Pd(0) for catalytic turnover.
This literature about this compound(676525-77-2)Name: [Ir(dtbbpy)(ppy)2]PF6has given us a lot of inspiration, and I hope that the research on this compound([Ir(dtbbpy)(ppy)2]PF6) can be further advanced. Maybe we can get more compounds in a similar way.
