Mixed ligand, monooxovanadium(V) complexes of Schiff bases with catechol, p-tertbutylcatechol or pyrogallol have been synthesized and characterized by various spectral techniques, such as FTIR, UV-vis, 51 V NMR and electrochemistry. All of these complexes exhibited a six coordinated VO 3+ center. The stability and the conversion of these complexes to pentacoordinated VO...
Pentafluorobenzyl (PFB) derivatives of chlorinated acetic and propionic acids were prepared adapting previously published methods to prepare PFB derivatives of non-chlorinated acids. Reaction of monochloro- and dichloroacetic acids and 2-chloro-, 2,2-dichloro- and 2,3-dichloropropionic acids with pentafluorobenzyl bromide (PFBBr) produced the PFB esters. Trichloroacetic acid reacted with PFBBr to...
