Application of 7650-91-1. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 7650-91-1, Name is Benzyldiphenylphosphine. In a document type is Article, introducing its new discovery.
Ambiphilic molecules, which contain a Lewis base and Lewis acid, are of great interest based on their unique ability to activate small molecules. Phosphine boronates are one class of these substrates that have interesting catalytic activity. Direct access to these phosphine boronates is described through the iridium-catalyzed C?H borylation of phosphines. An unconventional cationic iridium catalyst was identified as optimal for a range of phosphines, providing good yields and selectivity across a diverse class of phosphine boronates (isolated as the borane-protected phosphine). A complimentary catalyst system (quinoline-based silane ligand with [(COD)IrOMe]2) was optimal for biphenyl-based phosphines. Selective polyborylation was also shown providing bis- and tris-borylated phosphines. Deprotection of the phosphine boronate provided free ambiphilic phosphine boronates, which do not have detectable interactions between the phosphorus and boron atoms in solution or the solid state.
