, p. 9476 - 9482 (2016)
An efficient P-arylation of secondary phosphine oxides has been achieved through the ligand-free copper-catalyzed addition of H-P(O) bonds to in situ generated arynes at room temperature. This transformation provides a straightforward route to the formation of the aryl-P bond with wide functional group compatibility, which produces arylphosphine oxides in up to 99% yield.
Aryl group - A leaving group in arylphosphine oxides
Stankevi?, Marek,Pisklak, Jolanta,W?odarczyk, Katarzyna
, p. 810 - 824 (2016/01/20)
The treatment of triphenylphosphine oxide with organometallic reagents leads to the substitution of up to three phenyl substituents with the incoming carbon nucleophile. The replacement of the phenyl/aryl group in tertiary diarylalkylphosphine oxides or even aryldialkylphosphine oxides was also observed. Naphthyl-substituted phosphine oxides undergo Michael-type addition at the naphthyl group when treated with organolithium reagent.
Wittig reactions in water. Synthesis of new water-soluble phosphonium salts and their reactions with substituted benzaldehydes
Russell, Matthew G.,Warren, Stuart
, p. 7995 - 7998 (2007/10/03)
We report the synthesis of new phosphonium salts which are soluble and stable in basic aqueous solution. The Wittig reactions of these phosphonium salts with substituted benzaldehydes in aqueous sodium hydroxide are discussed. These reactions exclude the use of any organic solvents and the products are isolated by a simple filtration.
