Abstract

Symmetric secondary amines are readily obtained by heating a neat primary amine with 0.5 mol% of bis(dichloro[η5-pentamethylcyclopentadienyl]iridium). The products are isolated by direct distillation in good yields.

Key words

amines - dimerizations - homogeneous catalysis - hydrogen transfer - iridium
