Abstract
Twelve new multidentate poly(pyrazol-1-ylmethyl)benzene ligands , (5)-(16), have been synthesized by phase-transfer-catalysed alkylations of pyrazoles with poly( bromomethyl )benzenes, and their 1H and 13C n.m.r. spectra have been fully assigned. X-Ray crystal structure determinations have been carried out on the tetrachloropalladate salt of the diprotonated form of 1,4-bis(3,5-dimethylpyrazol-1-ylmethyl)-2,3,5,6-tetramethylbenzene and on hexakis (pyrazol-1-ylmethyl)benzene.
