cis-vinylphosphonates and 1,3-butadienylphosphonates by zirconation of 1-alkynylphosphonates
Quntar, Abed Al Aziz,Srebnik, Morris
, p. 1379 - 1381 (2001)
(equation presented) Addition of "zirconocene" to 1-alkynylphosphonates gives three-membered zirconacylces that can be hydrolyzed to cis-vinylphosphonates or further reacted with alkynes/hydrolysis to give substituted (Z,E)- and (E,E)-1,3-butadienylphosph
Inverting External Asymmetric Induction via Selective Energy Transfer Catalysis: A Strategy to β-Chiral Phosphonate Antipodes
Onneken, Carina,Bussmann, Kathrin,Gilmour, Ryan
, p. 330 - 334 (2019/12/11)
Enantiodivergent, catalytic reduction of activated alkenes relays stereochemical information encoded in the antipodal chiral catalysts to the pro-chiral substrate. Although powerful, the strategy remains vulnerable to costs and availability of sourcing bo
Nickel(II)-magnesium-catalyzed cross-coupling of 1,1-dibromo-1-alkenes with diphenylphosphine oxide: One-pot synthesis of (E)-1-alkenylphosphine oxides or bisphosphine oxides

A novel nickel(II)-magnesium-mediated cross-coupling of diphenylphosphine oxide with a variety of 1,1-dibromo-1-alkenes has been developed, which provides a powerful and general methodology for the stereoselective synthesis of various (E)-1-alkenylphosphine oxides or bisphosphine oxides, with operational simplicity of the procedure, good to high yields and broad substrate applicability. Mechanistic studies reveal that the reaction might involve a Hirao reduction, cross-coupling and Michael addition. Copyright
Copper-mediated selective cross-coupling of 1,1-dibromo-1-alkenes and heteronucleophiles: Development of general routes to heterosubstituted alkynes and alkenes
Jouvin, Kevin,Coste, Alexis,Bayle, Alexandre,Legrand, Frederic,Karthikeyan, Ganesan,Tadiparthi, Krishnaji,Evano, Gwilherm
, p. 7933 - 7947 (2013/01/16)
Efficient and general procedures for the cross-coupling of 1,1-dibromoalkenes and N-, O-, and P-nucleophiles are reported. Fine-tuning of the reaction conditions allows for either site-selective, double, or alkynylative cross-coupling, therefore providing
