Chemistry 209 - Experiment #4 - Aldehydes and Ketones
Fehling’s solution Reduction Aldehydes and ketones can be reduced to produce alcohols. The reducing agent of choice is LiAlH4 - lithium aluminium hydride Able to transfer a hydride ion to the partially positive carbon atom of the carbonyl group Must be carried out in anhydrous conditions (in et...
• Pt and Rh also used as catalysts. O Raney Ni O H H Tautormers Constitutional isomers in equilibrium with each other that differ in the location of a hydrogen atom and a double bond are called tautomers. A case of tautomerization occurs with ketones (aldehydes) that are in ...
In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibitssp2hybridization. Two of thesp2orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule...
Ketones and aldehydes have significantly different chemistry. There is only a minor difference between the chemistry of acetone and butanone, but there is a pretty big difference between the chemistry of acetone and acetaldehyde. To make a long story short, aldehydes are categorized differently ...

A ruthenium-catalysed multicomponent reaction provides rapid and tunable access to 1,3-dienyl-6-oxy polyketide motifs. An initial alkene–alkyne coupling produces unsymmetrical 3-boryl-1,4-dienes. Allylation of aldehydes and ketones with these products is highly diastereoselective and results in the fo...
