Graphite oxide and graphene oxides have been used as solid catalysts for the synthesis of 5,5-dialkyldipyrromethanes and calix[4]pyrroles in organic and aqueous solutions at room temperature.

Porosity and acidity of molecular sieve Al-MCM-41 (ca. 30 Angstroem pore diameter) plays a crucial role in the synthesis of novel calix(4)pyrroles; for the first time, Al-MCM-41 has been used as a solid acid catalyst to produce a number of calix(4)pyrroles with good selectivity and yields where zeolite HY (ca. 7.6 Angstroem pore diameter) yields mainly the linear chain dimer and no cyclic products.
