3. Calcium Chloride catalyzed Intramolecular Oxa Michael addition of 2’-Hydroxychalcone to Flavanone

Pramod Kulkarni

Volume 8, Issue 2 , Spring 2018, Pages 26-32

Abstract
  An efficient cyclization of 2’-hydroxychalcone to flavanone using calcium chloride as a catalyst was developed. The scope of the reaction was studied with substituted 2’-hydroxychalcone and these chalcones was converted into corresponding flavanone in good yield. The merits of this method ...  Read More

Volume 8, Issue 2 , Spring 2018, Pages 43-54

Abstract
  A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 ...  Read More

6. Theoretical study of conformational properties and the anomeric effect study of the 2- phosphinanes

Javad Azizian; Mahdieh Entezari; Hossein Anaraki Ardakanib; Shahab Zomorrodbakhsh

Volume 8, Issue 2 , Spring 2018, Pages 55-61

Abstract
  Ab initio HF/6-31G* Methode was employed to calculate  the bond length in 2- phosphinanes  when electronegative groups was at C-2 tend axial and equatorial positions. The magnitude of  the anomeric effect depends on the nature of the substituent, the effect of the substituent can be seen ...  Read More
