Fluoride-mediated phosphination of alkenes and alkynes by silylphosphines
摘要:
Regioselective phosphination of carbon-carbon unsaturated bonds by a fluoride-mediated reaction of silylphosphines is described. Alkenes and alkynes having a directing group, such as an aromatic or a carbonyl group, reacted to form a carbon-phosphorus bond under mild conditions. When an anhydrous fluoride source was applied in the presence of an electrophile, the corresponding three-component coupling product was obtained. (C) 2004 Elsevier Ltd. All rights reserved.

Here we report catalytic asymmetric hydrophosphination of α,β-unsaturated carbonyl derivatives using a chiral Mn(I) complex as a catalyst. Through H–P bond activation, various phosphine-containing chiral products can be accessed via hydrophosphination of various ketone-, ester-, and carboxamide-based Michael acceptors.

amido complex with a tridentate P,N,N ligand, which is easily synthesized from commercially available chemicals, is a remarkable efficient (pre)catalyst for the hydrophosphination of alkenes using secondary and primary aryl and alkyl phosphines and even PH3 as reagents.
Free radical additions of diphenylphosphine, phenylphosphine and ethylenebis(phenylphosphine) to the following species are described: alkynols, alkyne ethers, unsaturated carboxylic acids and esters and beta-lactones. In a number of cases, these lead to water-soluble phosphines. NMR spectroscopic characterization of all new products has been carried out.
