In summary, we have developed a green and highly efficient
method for the synthesis of tertiary amines by direct
formation of tertiary amines by interaction of aldehydes with
secondary amines using Pt NWs as catalyst under mild reaction
conditions. Pt NWs show an ultrahigh selectivity towards
tertiary amines and afford perfect yields just in 3 hours,
avoiding high temperature and pressure. Moreover, the
catalyst can also be easily recovered and recycled with no loss
of catalytic activity. We firmly believe that this procedure is an
attractive option in organic synthesis with potential for
industrial applications.
