ChemInform Abstract
α-Substituted nitro compounds such as (I), (III), and (VI) are reduced by the title hydride to give the corresponding nitroalkanes. Applying low tributyltin hydride concentration the nitroalkane (VIIb) is accompanied by (VIII), a product of cyclization. No cyclic products are observed in the reduction of (IX), indicating that the bimolecular reduction of the intermediate α-nitroalkyl by Bu3SnH is faster than cyclization.
