文摘

A novel organic-inorganic hybrid solid acid [MIMBS]₃PW₁₂O₄₀ has been successfully prepared. It showed high catalytic activity for N-substituted pyrroles through the cyclocondensation of primary amines with 1,4-dicarbonyl compounds. The solid acid catalyst is stable and can be easily recovered and reused without losing its activity in its efficiency. In addition, a plausible mechanism for the catalytic action of [MIMBS]₃PW₁₂O₄₀ has been introduced.
