Ruthenium-Catalyzed Gram-Scale Preferential C–H Arylation of Tertiary Phosphine

2019
期刊 Organic Letters
A general protocol for site-preferential mono-C−H arylation of tertiary phosphine ligands catalyzed by a ruthenium(II) complex was devised. This protocol gives access to a series of modified Buchwald−biaryl monophosphines on a gram scale in moderate to excellent yields. A catalytic cycle is proposed derived from knowledge of the intermediates observed by ESI-MS. Importantly, these monoarylated products could be further transformed into dibenzophosphole derivatives.
