Synthesis of Tetra-Imidazolylmethyl Bi-Phenol Compounds

Tetra-imidazolylmethyl bi-phenol compounds (3a,3b) are efficiently synthesized and structurally confirmed. 4, 4 -dihydroxydiphenylpropane and 4,4 -biphenol are respectively treated with paraformladehyde to give tetra-hydroxyl derivative (2a,2b). Treatment of (2a,2b) with imidazole at 130 to 140℃and 160 to 170℃in DMF gives the corresponding tetra-imidazolylmethyl bi-phenol (3a,3b). The chemical yields of 3aand 3bare 57% and 59.3% respectively. Tetra- imidazolmethyl bi-phenol compounds obtained have been confirmed by MS,1HNMR, IR measurements and elemental analyses.
