The reaction of aliphatic and aromatic secondary and tertiary N-tritylamines with lithium powder and a catalytic amount of naphthalene led to reductive detritylation affording the corresponding amines in good yields. The trityl group could selectively be removed in the presence of an allyl or a benzyl group.
