HYDRODEMETHOXYLATION, HYDRODECHLORATION, HYDRODESULFURIZATION, AND HYDRODEAMINATION OF NEUTRAL X-SUBSTITUTED-CYCLOHEXADIENYL)TRICARBONYLMANGANESE COMPLEXES (X=OME, CL, SPH, NET(2)) UPON TREATMENT WITH HYDRIDE AND THEN ACID - CINE AND TELE NUCLEOPHILIC SUBSTITUTIONS

Treatment of X-substituted-cyclohexadienyl)tricarbonylmanganese comple xes (X = alkoxy, halogeno, dimethylamino and thio) with hydrides and a proton source gave eta(5)-cyclohexadienyl complexes resulting from a cleavage of the C-O, C-Cl, C-N and C-S bonds: The eta(3)-substituted c yclohexenyl intermediates underwent elimination of an agostic hydrogen and the alkoxy, halogeno, amino, or thio group.
