5-Norbornene-2-carboxaldehyde was used in transition metal-catalyzed synthesis of norbornene-derived homopolymers having pendent t-Boc-protected quinizarin moieties for patterned fluorescence images. It acts as Diels-Alder adduct of acrolein and cyclopentadiene. It can be used as protected form of acrolein, from which the double bond may be liberated by cycloreversion, e.g. in a useful synthesis of 2-vinylimidazole.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
