The cerium(III) derivative of acetonitrile undergoes addition with ketones efficiently. It adds effectively to hindered ketones and gives 1,2-adduct exclusively with conjugated enones.

The SmI2-mediated coupling of alpha-bromoacetonitrile and alpha-bromopropionitrile with aliphatic ketones and aldehydes produces beta-hydroxynitriles in good yields. Reactions typically proceed with little diastereoselectivity, but selectivity enhancement occurs with the addition of tetra-n-hexylammonium bromide. (C) 2000 Elsevier Science Ltd. All rights reserved.
