Aldol Condensation of Butan-2-one and Pentan-3-one on an Activated Alumina as Monotored via in-situ Carbon-13 Nuclear Magnetic Resonance Spectroscopy

Conventional (13)C nuclear magnetic resonance spectroscopy is used to monitor the reactions of butan-2-one and pentan-3-one adsorbed on alumina.Both reaction sequences proceed via successive aldol condensations.The products observed for butan-2-one (5-methyl-4-hepten-3-one and 4-hydroxy-4-methylpentan-2-one) are those expected for homogeneous base catalysis.A J-modulated spin-echo sequence demonstrates that 5-ethyl-4-methyl-5-hepten-3-one, the β,γ condensation product, is obtained using pentan-3-one.The results demonstrate that conventional (13)C n.m.r. can be effectively used to distinguish reaction pathways and products for surface catalysed reactions.
