of alcohols and amines to
form aldimines represents an environmentally benign methodology in
organic chemistry. This has been accomplished in recent years mainly
with precious-metal-based catalysts. We present the dehydrogenative
coupling of alcohols and amines to form imines and H2 that
is catalyzed, for the first time, by a complex of the earth-abundant
Mn. Detailed mechanistic study was carried out with the aid of NMR
spectroscopy, intermediate isolation, and X-ray analysis.
