LIGAND CHANGE EFFECT IN CROWN ETHER PHASE TRANSFER CATALYST DURING THE REACTION BETWEEN AQUEOUS POTASSIUM THIOCYNATE AND P-NITROBENZYL BROMIDE
Journal Title: Indian Journal of Scientific Research - Year 2017, Vol 8, Issue 1
Abstract
Various ligands changes in phase transfer catalyst named 18-Crown-6 during the reaction between Aqueous potassium thiocynate and P-Nitrobenzyl bromide resulting significantly change in reaction rate.Change in Ligand lipophilicity makes valuable impact in catalyst performance. When electron withdrawing carbonyl group function act as a ligand then lower reaction rate observed, reverse is true when electron releasing alkyl group function act as a ligand than higher reaction rate is observed .
