Montmorillonite K10: Catalyst for friedel-crafts alkylation of indoles and pyrrole with nitroalkenes under solventless conditions

An, Li-Tao,Zhang, Li-Li,Zou, Jian-Ping,Zhang, Guang-Liang

experimental part, p. 1978 - 1984 (2010/09/07)

Montmorillonite K10 was found to catalyze the Michael addition of indoles or pyrrole with nitroalkenes efficiently under solventless condition. The short reaction time, simple workup, and excellent yields were noteworthy. The green catalyst could be reused for three runs without considerable variation in yield. Copyright
