The reduction process is rather general, rapid and gives a high yield of product. It operates for electron-rich and electron-poor nitroarenes and tolerates ortho substituents, halides, and other functional groups such as ketones, alcohols, vinyl, nitrile, and benzamides. We have also been able to reduce the reaction times to 15 minutes (eg, Table [2] , 2c-l). This reaction can also be carried out thermally with yields comparable to those observed for the ...
