A new relay C–H functionalization of di([1,1′-biphenyl]-2-yl)phosphine oxide to obtain esterified and hydroxylated products with different hypervalent iodines as oxidants under palladium catalysis is disclosed. This reaction provides a more effective and concise strategy for the synthesis of novel structural hybrid-arylcyclophosphorus ligand precursors with a wide range of substrates and good functional
A new regioselective synthetic methodology for benzo[b]phosphole derivatives has been developed. Thus, a range of functionalized benzo[b]phosphole oxides could be synthesized via Rh(III)-catalyzed C–H alkenylation of arylthiophosphinamides with alkynes followed by formal phospha-Friedel–Crafts cyclization.
已经开发了一种新的苯并[ b ]磷衍生物的区域选择性合成方法。因此,可以通过Rh(III)催化的芳硫代次膦酰胺与炔烃的C–H烯基化反应,然后再进行正膦-Friedel-Crafts环化反应,来合成一系列功能化的苯并[ b ]氧化物。
