A highly efficient catalyst for Suzuki coupling of aryl halides and bromoarylphosphine oxides
摘要:
The biphenyl-based phosphine, P(o-C6H4C6H4Me)Ph-2, is a moderately bulky and electron-rich phosphine, which has been successfully applied to the palladium catalyzed Suzuki coupling of activated and deactivated aryl halides as well as bromoarylphosphines and bromoarylphosphine oxides, with low catalyst loading and good to excellent conversions and turnovers.

(Phosp)hole in one: A palladium‐catalyzed synthesis for directly assembling phosphole skeletons fromtriarylphosphinesthrough CH and CP bond cleavage was developed. This approach overcomes several of the limitations of the so far reported methods. Phospholes bearing a range of functionalities (including Br, F, CO2Me, Ac, and CN) and an array of fused rings (naphthalenes, anthracenes, furans, and
在一个(Phosp)孔:一个钯催化合成的用于从至C三芳基膦直接组装磷杂环骨架 H和13 C P键裂解被开发。这种方法克服了迄今为止报道的方法的一些局限性。可以容易地合成具有一系列功能性(包括Br,F,CO 2 Me,Ac和CN)的磷脂和一系列稠环(萘,蒽,呋喃和吡咯)。

of newphosphines through Rh- or Ru-catalyzed C–H bond functionalizations, synthetic access to more diverse phosphines remains a challenge. We describe an efficient process for the rhodium-catalyzed phosphorus(III)-directed hydroarylation of internal alkynes to generate various alkenylated and 2′,6′-dialkenylated biarylphosphines with high selectivity. A range of diverse alkynes and phosphines were

Palladium-catalyzed arylation of (diisopropylphosphoryl)biphenyl skeleton derivatives by the P(O)R2 directed C-H functionalization was reported. The related products were obtained in high regioselectivity and good functional group tolerance was observed. This reaction provided a new and efficient pathway for the synthesis of polyaromatic monophosphorusligands.

situ modification of biaryl-type monophosphines with hydrosilanes through a PIII -chelation-assisted dehydrogenative silylation reaction. A series of ligands containing silyl groups with different steric and electronic properties were obtained with excellent regioselectivities. This method offers many advantages, including the use of commercially available phosphines, no requirement for an external ligand

Modification of commercially available monophosphine ligands with either aryl bromides or chlorides by rhodium(I)‐catalyzed, tertiaryphosphine directed C−H activation is described. A series of ligand libraries containing mono‐ and diaryl‐substituted groups, having different steric and electronic properties, were obtained in high yields. Based on the outstanding properties of their parent scaffolds
