Abstract
The reaction of pyrrol with cymantrenecarboxaldehyde in acetic acid re sults in 5,10,15,20-tetracymantenylporphyrin (1) and 5,10,15-tricymant renylcorrol (2). Porphyrin synthesis according to Lindsey's method onl y affords compound 1 in high yield. The NH-tautomerism in molecules 1 and 2 was investigated by dynamic NMR spectroscopy. It was shown that free rotation of the (CO)(3)MnC5H4 fragments around the bond with the carbon atoms in the meso-positions of the porhpyrin macrocycle occurs.
