Palladium-Catalyzed Cross-Coupling ofH-Phosphinate Esters with Chloroarenes
摘要:
The palladium-catalyzed cross-coupling reaction between H-phosphinate esters and chloroarenes or chloroheteroarenes Is described. This reaction is the first general metal-catalyzed phosphorus carbon bond-forming reaction between a phosphorus nucleophile and chloroarenes.
An Eco-Friendly and Efficient Photoinduced Coupling of Alkenes and Alkynes with H-Phosphinates and Other P(O)H Derivatives Under Free-Radical Conditions
An efficient method for the synthesis of organophosphorus compounds from alkenes or alkynes and P(O)H compounds was developed under neutral and free-radicalconditions. This methodology can be achieved without solvent, at room temperature in an open air system, using only 0.1 equiv. of 2,2-dimethoxy-2-phenylacetophenone (DPAP) as photoinitiator and an equimolar ratio of unsaturated compound and P(O)H
