Photolysis of the cycloadduct of a 1,2-dihydrophosphinine oxide with N-phenylmaleimide in the presence of protic species: New aspects on the mechanism of the fragmentation of a 2-phosphabicyclo[2.2.2]octene
Keglevich, Gyoergy,Steinhauser, Kinga,Ludanyi, Krisztina,Toke, Laslo
, p. 49 - 53 (1998)
Phosphabicyclo[2.2.2]octene 2 is useful in the UV light mediated phosphorylation of protic species. Experiments suggest that the fragmentation takes place according to concurrent EA and AE mechanisms.
Synthesis and use of 6-, 7-and 8-membered P-heterocycles
Keglevich, Gyoergy,Toeke, Laszlo,Steinhauser, Kinga,Novak, Tibor,Ludanyi, Krisztina
, p. 593 - 596 (1999)
The synthesis of new families of P-heterocycles by reductive modifications, ring enlargement and Diels-Alder cycloaddition is described.
Novel 2-Phosphabicyclo[2.2.2]oct-5-ene Derivatives and Their Use in Phosphinylations
Keglevich, Gyoergy,Kovacs, Janos,Koertvelyesi, Cavaes,Parlagh, Gyula,Imre, Timea,Ludanyi, Krisztina,Hegedus, Laszlo,Hanusz, Miklos,Simon, Kalman,Marton, Andrea,Marosi, Gyoergy,Toke, Laszlo
, p. 97 - 106 (2004)
The [4 + 2] cycloaddition of the double-bond isomers (A and B) of dihydrophosphinine oxide 1 afforded novel phosphabicyclo[2.2.2]oct-5-ene derivates (2-4), formation of which was justified by PM3 semiempirical calculations. The compounds of dimer type (2-
Stereochemistry at the Phosphorus Atom during Palladium-catalysed Formation of Carbon-Phosphorus Bonds and Mechanistic Implications
Xu, Yuanyao,Zhang, Jing
, p. 1606 (1986)
The reaction of (R)-(+)-isopropyl methylphosphinate (5) with bromobenzene in the presence of Pd(0) catalyst and triethylamine to afford (S)-(-)-isopropyl methylphenylphosphinate (6) proceeds with complete retention of configuration via a front-sided attack by phenylpalladium bromide on the phosphorus nucleophile.
PHOSPHORORGANISCHE VERBINDUNGEN 119. DIE ASYMMETRISCHE INDUKTION ALS MECHANISTISCHER WEGWEISER BEI DER VERESTERUNG VON METHYLPHENYLPHOSPHINSAEURE-HALOGENIDEN UND PSEUDOHALOGENIDEN IN GEGENWART OPTISCH AKTIVER AMINE
Weidert, Peter J.,Geyer, Ekkehard,Horner, Leopold
, p. 255 - 260 (2007/10/02)
The reaction of rac. methylphenylphosphinicacid-halides and pseudohalides MePhP(O)X (X = F, Cl, CN, OC6H4NO2(p)) with alcohols ROH (R = Me, PhCH2, CF3CH2 and i-Prop) leads in the presence of the optically active amines 1-5 to partial optically active esters.The optical induction is between 1 and 14 percent.A mechanism inclidung five- and six bonded phosphorus intermediates is proposed.Key words: Chiral phosphinic acid halides; chiral phosphinicesters; optical induction; optically active amines as inductors; esterification; mechanism
