General description
Crotonaldehyde on hydrogenation over Pt/SiO2 and Pt/TiO2 catalysts yields butyraldehyde and crotylalcohol depending on the size of the Pt particles and the promotion by surface oxides. It forms adducts with oligodeoxynucleotides containing 1,N2-deoxyguanosine residues and forms crosslinks with the tetrapeptide Lys-Trp-Lys-Lys.
Application
Crotonaldehyde was used to study the kinetics of the reaction of acrolein,crotonaldehyde and pivalaldehyde with Cl atoms.
