The 1H nmr spectra of 1, 3-di-tert-butyl-2-methoxybenzenedicarbonyltriphenylphosph... (5) and some related compounds at low temperatures show the presence of two species which interconvert with free energy of activation near 50 kJ mol-1. The species differ in the orientation of the methoxy with respect to the chromium, since the same type of process is observed in a chelate complex in which a phosphinite ligand on chromium is also ...
