Hydroxymethyl tellurophenes

The title compound, a heterocycle with several interesting structural features, was recently synthesized by the condensation of 2,5-bis(l-phenyl-l-hydroxymethyl)tellurophene, pyrrole,... 

The metal-free condensation of fr(2-formylphenyl)telluride with a series of diamines afforded the macrocyclic tellurium Schiff base macrocycles attempted complexation with Pt(II) and Hg(II) afforded transmetalated products <04JOM1452>. Reduction of the Schiff base components of these chalcogenaza macrocycles gave rise to more robust and flexible macrocycles, which form the desired Pd(II) Tie,iV,jV, Tie-complex <04CC322>. The related Se-derivatives are also therein reported. 5,10-Diphenyl-15,20-di(4-methoxyphenyl)-21-tellura-porphyrin was prepared (18%) by the acid-catalyzed condensation of 2,5-6w(l-phenyl-l-hydroxymethyl)tellurophene, pyrrole, and 4-methoxybenzaldehyde, followed by oxidation with /j-chloranil <04OM4513>.
