an air-stable dianthracenyl monophosphine ligand (diAnthPhos) which can be prepared in two steps from commercially available anthracene derivatives. The ligand exhibits excellent efficiency for palladium-catalyzed coupling reactions. In particular, Miyaura borylation of heterocycle-containing electrophiles can be facilitated employing the diAnthPhos ligand with a broad substrate scope and low catalyst
在这里,我们提出了一种空气稳定的二蒽基单膦配体(diAnthPhos),它可以由市售的蒽衍生物分两步制备。该配体对于钯催化的偶联反应表现出优异的效率。特别地,使用具有宽底物范围和低催化剂负载的diAnthPhos配体可以促进含杂环亲电试剂的宫浦硼化。通过对含杂芳基的底物进行一锅Miyaura硼化/ Suzuki偶联方案,进一步证明了新配体的宝贵合成效用。
