An efficient solvent-free synthesis of meso-substituted dipyrromethanes using SnCl2•2H2O catalysis

Kabeer Ahmed Shaikh, Vishal A. Patil, B. P. Bandgar


Highly rapid and simple methodology has been developed for the quantitative synthesis of meso-substituted dipyrromethanes from lowest pyrrole/aldehyde ratio. The method was carried out by using SnCl2•2H2O as a catalyst under solvent free condition. The method is environmentally friendly, easy to workup, and gives excellent yield of the products.
