Abstract

Intramolecular exchange processes in the molybdenum complexes [Mo(CO)(HC≡CR)₂(Cp)] ⁺ (R = t-Bu, Ph, CO₂Me, Me) were studied by using 2-D NMR exchange techniques in which kinetic parameters for the two independent alkyne rotations are derived from the intensities of the off-diagonal cross peaks. The exchange rates were largely governed by the sterlc bulk of the alkyne ligands. The 2-D NMR technique was very effective for thermally sensitive compounds in slow exchange.
