First heterogeneous ligand- and salt-free larock indole Synthesis

A new ligand- and salt-free procedure using heterogeneous palladium catalysts for the Larock indole and benzofuran synthesis is reported. After optimisation of the reaction conditions, good to high isolated yields have been achieved for a variety of structures. Recycling studies have shown that the palladium catalysts can be readily recovered and reused. Reactions and recovery of the palladium catalysts can be carried out in the presence of air, without any particular precaution.

SUBSTITUENT INFLUENCE ON THE INDOLIZATION WITH PCl3 OF SOME o,m,p-SUBSTITUTED PHENYLHYDRAZONES

The indolization of deoxybenzoin o,m,p (Me, MeO, Cl), p-NO2 and m-EtO-phenylhydrazones (1) by the above reaction has been examined.All the reactions are carried out at room temperature and high yields of the corresponding indoles (2) are obtained even whe
