Abstract
Abstract: The stereodynamics in 1, 4-dimethoxy-2, 3, 5, 6-tetraethylbenzene (5), 1, 4-bis (methoxymethy1)-2, 3, 5, 6-tetraethylbenzene (6), and 1, 4-dineohexyI-2, 3, 5, 6- tetraethylbenzene (7) and their respective tricarbonylchromium complexes, 5 (Cr), 6 (Cr), and 7 (Cr), have been studied by variable-temperature NMR techniques. Barriers to rotation about the sp2sp3 bonds for 5 7 and 5 (Cr)-7 (Cr) have been determined using the ...
