Efficient potassium hydroxide promoted P-arylation of aryl halides with diphenylphosphine

A simple synthetic method of triarylphosphine compounds by KOH-promoted P-Arylation reaction of aryl halides with diphenylphosphine is presented. Notably, this transformation could smoothly proceed with high yields under transition-metal-free and mild reaction conditions. In addition, this protocol is valuable for industrial application due to the convenient operation and readily accessible aromatic halides. A possible explanation of the reaction mechanism was proposed based on the experimental data.

Preparation method of phosphorus center chiral compound

The invention discloses a preparation method of a phosphorus center chiral compound. The preparation method specifically comprises the following step: in the presence of an oxidizing agent, palladiumsalt and an N-single protected chiral amino acid ligand, carrying out C-H bond alkenylation reaction on 2-pyridyl diarylphosphine oxide shown as a formula (II) and an olefin derivative shown as a formula (III) to generate the phosphorus center chiral compound shown as a formula (I). The method has good adaptability to different types of substituents in various 2-pyridyl diarylphosphine oxides andolefins, especially olefins with large steric hindrance, and has the advantages of stable yield and excellent enantioselectivity.

Visible-Light-Promoted Transition-Metal-Free Phosphinylation of Heteroaryl Halides in the Presence of Potassium tert-Butoxide

A novel visible-light-promoted C-P bond formation reaction in the absence of both transition metal and photoredox catalysts is disclosed. By employing easily available and inexpensive heteroaryl chlorides/bromides as substrates, a variety of heteroaryl phosphine oxides were obtained in moderate to good yields. This strategy provides a simple and efficient route to heteroaryl phosphine oxides.
