  Reactions of Co₄(CO)₁₂ and Cr(CO)₆ with Dibenzothiophene and Benzothiophene

  摘要：

  Reaction of Co-4(CO)(12) With dibenzothiophene (DBT) gives (eta(6)-DBT)Co-4(CO)(9) (1), in which one arene ring of DBT is eta(6)-coordinated to a Co. This cluster 1 reacts with Cr(CO)(6) to give (eta(6)-DBT)Cr(CO)(3) and [CO)(3)Cr](2)(mu-DBT) but reacts with Cr(CO)(3)(NCMe)(3) to give the desulfurized (eta(6)-benzene)Co-4(CO)(9) (4). Benzothiophene yields the same desulfurized product 4 upon reaction with Co-4(CO)(12).

  摘要：

  The complex formation of dibenzothiophene with chromium carbonyl complexes of the general formula L3Cr(CO)(3) (L = Py, NH3, or CO) afforded eta(6)-C12H8Cr(CO)(3) (1). In the presence of tetramethylethylenediamine, complex I was selectively metallated with BuLi at position 4 of the coordinated ring to form eta(6)-4-LiC12H8SCr(CO)(3) (2). In decane, the tricarbonylchromium group is reversibly and intramolecularly migrates from the unsubstituted to Substituted ring due to the inter-ring haptotropic rearrangement (IRHR) at 130degreesC for 100 h. In decane, the rate constant of IRHR was estimated experimentally by H-1 NMR spectroscopy and theoretically by the density functional theory (DFT).

  Herein, a general strategy for the regioselective dearomative 1,2-hydrocyanoalkylation of chromium-bound (hetero)arenes with simple alkylnitriles as pronucleophiles was disclosed, providing rapid access to 1,3-cyclohexadienes possessing useful alkylnitrile groups. The versatility of this methodology further enabled a selective dearomative deuteration reaction. Finally, synthetic applications of the method in the formal synthesis of natural products, including erysotramidine, demethoxyerythratidinone, and morphine, were demonstrated.

  摘要 本文公开了一种以简单的烷基腈为代核亲和剂，对铬结合（杂）烷进行区域选择性脱芳基 1,2-氢氰烷基化反应的一般策略，从而快速获得具有有用烷基腈基团的 1,3-环己二烯。这种方法的多功能性进一步促成了一种选择性脱芳基氘化反应。最后，还展示了该方法在天然产物（包括麦饭石苷、去甲氧基赤桔梗酮和吗啡）的正式合成中的应用。
