摘　　要：Samarium diiodide （SmI2） was found to be an efficient catalyst for the condensation of o-phenylenediamine and ketones to afford the corresponding 2,3-dihydro-1H-benzo[b][1,4]-diazepines in moderate to excellent yields under very mild and solvent-free conditions. The real active species here was suggested to be a Sin（Ⅲ） intermediate formed in situ and the mechanism of the present reaction was proposed.Samarium diiodide （SmI2） was found to be an efficient catalyst for the condensation of o-phenylenediamine and ketones to afford the corresponding 2,3-dihydro-1H-benzo[b][1,4]-diazepines in moderate to excellent yields under very mild and solvent-free conditions.
