  Oxidative Cleavage of Methyl Ethers Using the HOF.cntdot.CH3CN Complex

  摘要：

  HOF . CH3CN complex, made easily by bubbling fluorine diluted with nitrogen through aqueous acetonitrile, proved to be a suitable oxidizer for various methyl ethers. Secondary ethers are oxidized to ketones and even to lactones via Baeyer-Villiger type of oxidation. The reaction is ionic, and the reagent's electrophilic oxygen attacks the relatively electron rich C-H bend alpha to the ether moiety. It was found that the more sterically hindered is the C-H bond in question, the slower the reaction. In cases where this bond is an electron poor one as in benzoin methyl ether (9), no reaction takes place. When labeled (HOF)-O-18 . CH3CN is used on a O-16 methyl ether, the resulting ketone possesses only the heavier oxygen isotope. Primary methyl ethers are somewhat slower to react, but they too were oxidized in very good yields to acids via the corresponding aldehydes.

  Methoxy 13C chemical shifts in methoxycyclohexane derivatives may be rationalized in terms of rotamer populations about the C–OMe bond and δ1-effects caused by steric interaction of the methoxy-group with substituents at the neighbouring 2- and 6-positions. Information on rotamer populations is obtained also from the 13C chemical shifts of C-2 and C-6, and from the three-bond coupling between the proton

  Trimethylsilyl triflate is a powerful silylating agent for organic compounds and acts as a catalyst which accelerates a variety of nucleophilic reactions in aprotic media. The reactions proceed via one-center, electrophilic coordination of the silyl group to hetero functional groups and exhibit unique selectivities.

  A catalytic, light-promoted hydrosilylative cleavage reaction of alkyl ethers is reported. Initial studies are consistent with a mechanism involving heterolytic silane activation followed by delivery of a photohydride equivalent to a silyloxonium ion generated in situ. The catalyst resting state is a mixture of Cp*Ir(ppy)H (ppy = 2-phenylpyridine-κC,N) and a related hydride-bridged dimer. Trends in
