Bond Rotation in an Aromatic Carbaporphyrin: Allyliporphyrin

Allyliporphyrin is a carbaporphyrin that has replaced one pyrrole with an allyl group. Dynamic behavior (bond rotation) was observed by variable temperature H NMR and 2D‐NOESY NMR spectroscopy and theoretically examined by DFT calculations. These studies revealed that well‐defined bond rotation was... Full description
