(1-Hydroxyalkyl)- and (1-hydroxy-1-methylalkyl) ferrocenes (α-ferrocenyl carbinols) have been synthesized and their high resolution 1H-NMR spectra studied as a function of the stereochemistry of the substituted connected to the cyclopentadienyl ring. It was found that when α-ferrocenyl carbinol contains a chiral center in the substituent, the 2,5- and 3,4-positions in the cyclopentadienyl ring become pairwise diastereotopic and magnetically unequivalent.
