                                    Aliphatic aldehydes underwent trimerization in the presence of a catalytic amount of Cp*Sm-2(thf)(2) under ambient conditions to form 1,3-diol monoesters in good yields. For example, the reaction of acetoaldehyde catalyzed by Cp*Sm-2(thf)(2) gave 4-acetoxy-2-butanol (2a) and 3-acetoxy- 1-butanol (3a) in 86% yield. (C) 1998 Elsevier Science Ltd. All rights reserved.
