Iridium-N,P-ligand-catalyzed enantioselective hydrogenation of diphenylvinylphosphine oxides and vinylphosphonates
Cheruku, Pradeep,Paptchikhine, Alexander,Church, Tamara L.,Andersson, Pher G.
supporting information; experimental part, p. 8285 - 8289 (2009/12/02)
Diphenylvinylphosphine oxides and di- and trisubstituted vinylphosphonates have been employed as substrates in iridium-catalyzed asymmetric hydrogenations. Complete conversions and excellent enantioselectivities (up to and above 99percent ee) were observe

Acylphosphonates as Substrates for Wittig and Horner-Wittig Reactions. Unusual Stereoselectivity in the Synthesis of β-Phosphinoylacrylates
Harris, Roger L. N.,McFadden, Helen G.
, p. 417 - 424 (2007/10/02)
Phosphorus-stabilized carbanions with additional stabilizing groups react with dialkyl acylphosphonates (alkanoyl- and aroyl-phosphonates) to give fair to good yields of dialkyl vinylphoshponates, with some limitations imposed by competing side reactions
