15-Asymmetric induction during nucleophilic additions to arene­tricarbonyl­chromium complexes: tri­carbonyl­(η6-1-methyl-4-{spiro­(1R2S)-177-trimethyl­bicyclo­2.2.1heptane-32′-13-dioxolan-2-yl­oxy}benzene)­chromium

摘要

The tricarbonyl­chromium unit bound to the arene ring of the chiral title complex, [Cr(C19H26O3)(CO)3], is rotated by ca 25° in agreement with the proposed mechanism for 1,5-asymmetric induction of nucleophilic attack.
