Polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3): An efficient catalyst for the synthesis of chromenylphenylpropanones
An efficient synthesis of chromenylphenylpropanone derivatives as warfarine-like analogues was developed by the Michael addition of 4-hydroxycoumarin to α,β-unsaturated compounds in the presence of polyvinylpolypyrrolidone supported antimony(III) chloride (PVPP-SbCl3) as a new polymeric Lewis acid catalyst in chloroform at reflux conditions without formation of 2,4-...

متن کامل1,4,8,11-Tetraazacyclotetradecane antimony(III) sulfide.
Poly[1,4,8,11-tetraazacyclotetradecane(2+) [hepta-mu-sulfido-trisulfidohexaantimony(III)]], {(C10H26N4)[Sb6S10]}n, consists of novel [Sb6S10]2- layers containing Sb2S2, Sb4S4 and Sb7S7 hetero-rings, which are separated by macrocyclic amine molecules. The macrocyclic amine molecules are disordered over two crystallographically distinct positions and are diprotonated in order to balance the charg...
متن کاملA Stable Solution of Antimony for the Treatment of Kala-Azar
was likely to be the last word in the treatment of this disease. One disadvantage it suffers is that dissolved in distilled water it does not make a very stable solution and it cannot therefore be supplied as a solution, but has to be issued in dry form in sealed ampoules which should be dissolved shortly before use*. There are obvious advantages in having the drug in fluid form ready for immed...
متن کاملElectronic Spectra and Photochemistry of Tin(II), Lead(II), Antimony(III), and Bismuth(III) Bromide Complexes in Solution
The electronic spectra o f bromo complexes o f main group metal ions with an s2 electronic configuration (SnBr3~, PbBr3~, PbBr42_, SbBr4~, SbBr63~, BiBr4~, BiBr63~) in acetonitrile show long-wavelength absorption bands which are assigned to metal-centered sp transitions. Com pared to the corresponding chloro complexes the sp bands o f the bromo complexes appear at longer wavelength due to sp/L...
