Considering the synthetic value of phosphonates, developing powerful catalytic methods for the phosphonylation of C(sp2)-H bonds is important. Herein, we achieve a visible-light-induced external oxidant-free oxidative phosphonylation of C(spsu
Synthesis of Lipophilic Crown Ethers with Pendant Phosphonic Acid or Phosphonic Acid Monoethyl Ester Groups
Czech, Bronislaw P.,Desai, Dhimant H.,Koszuk, Jacek,Czech, Anna,Babb, David A.,at al.
, p. 867 - 875 (2007/10/02)
Synthetic routes to fifteen lipophilic crown ether phosphonic acid monoethyl esters and nine lipophilic crown ether phosphonic acids are described.For both classes of crown ethers which have pendant, proton-ionizable groups, the crown ether ring sizes are
