M. Minato et al., REDUCTIONS OF C=O AND C=N GROUPS WITH THE SYSTEMS COMPOSED OF (ETA(5)-C5H5)(2)MOH2 AND ACIDS, Journal of organometallic chemistry, 569(1-2), 1998, pp. 139-145
Selective reductions of organic compounds, such as carbonyl compounds
and imines, using a system composed of Cp2MoH2 and acids are examined.
This system can reduce the substrates under mild conditions. Extremel
y high diastereoselectivity was achieved in the reduction of 4-t-butyl
cyclohexanone. The reactivity of imines depends on their structure. Ar
omatic imines are found to be more reactive than aliphatic imines. (C)
