Abstract
Azides were converted to the corresponding carbamates using a system of 20 mol% of decaborane (B10H14) and 20 weight% of 10% Pd/C in methanol in the presence of di-tert- butyl dicarbonate at rt in high yields and to the corresponding amines using a system of 10 mol% of decaborane and 20 weight% of 10% Pd/C in methanol in the absence of di-tert- butyl dicarbonate at rt in high yields.
