Promoting Reductive Tandem Reactions of Nitrostyrenes with Mo(CO)(6) and a Palladium Catalyst To Produce 3H-Indoles
The combination of Mo(CO)(6) and 10 Mol % of palladium acetate catalyzes the transformation of 2-nitroarenes to 3H-indoles through a tandem cyclization-[1,2] shift reaction of in situ generated nitrosoarenes. Mo(CO)(6) appears to have dual roles in this transformation generate generate CO and promote C-N bond formation to increase the yield of the N-heterocycle product.
