摘要：

Self-aldol condensation of an unmodified aldehyde has been effected by 3-N-methylaminoprophylated silica as a catalyst in supercritical carbon dioxide, to give an alpha,beta-unsaturated aldehyde (enal). Aldehydes having acid or base-sensitive substituents provided desired enals. (C) 2004 Elsevier Ltd. All rights reserved.
