Description

Reductionof -nitronaphthalene with su des was studied. The selectivity of the reduction to a-aminonaphthalene was decreased with increasing concentration of sulfides. lt was found desirable to use sulfides which aged for one day 3 times more than the ameunt theeretically required. The higher the reductien temperature, the higher was the selectivity to a-aminonaphthalene. The presence of FeCls improved the selectivity, while the increase in OHm concentration decreased the selectivity to a-aminonaphthalene# From these results, the optimum reduction condition to give 93% of a-aminonaphthalene was established.
