Poly(pyrazol-1-ylmethyl)benzenes: New Multidentate Ligands

Article abstract of DOI:10.1071/CH9951587

Twelve new multidentate poly(pyrazol-1-ylmethyl)benzene ligands, (5)-(16), have benn 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.
