The spatial extent of orientational short-range order in liquid and rotationally disordered phases of two halogen-substituted methanes are examined by means of neutron diffraction. The pair distribution functions measured within the liquids are compared to those corresponding to the rotator-phase crytals where the separation between orientational and positional correlations is enabled by the pr...

Enantiomerically pure (S,S)-1,2-bis[(o-alkylphenyl)phenylphosphino]ethanes (o-alkylphenyl = o-methylphenyl, o-ethylphenyl, o-isopropylphenyl, 5',6',7',8'-tetrahydronaphthyl), (S,S)-1,2-bis(alkyl-methylphosphino)ethanes (alkyl = t-butyl, 1-adamantyl, 1-methylcyclo-hexyl, 1,1-diethylpropyl, cyclopentyl, cyclohexyl) (abbreviated as BisP*), and (R,R)-1,1-bis(alkylmethylphosphino)methanes (alkyl = i...

Degradation of tetrachloromethane was examined in the three strictly anaerobic bacteria, Acetobacterium woodii. Desulfobacterium autotrophicum and Methanobacterium thermoauwtrophicum. When incubated under anaerobic conditions in reduced buffer, suspensions of each organism degraded CCI4 by both reductive and substitutive mechanisms. The products formed included less-highly chlorinated methanes ...

A method for synthesis without protecting groups of bis(indolyl)methanes by the (η-benzyl)palladium system generated from a palladium catalyst and benzyl alcohol in water is developed. This domino protocol involves C3–H bond activation/benzylation of indole–carboxylic acids and benzylic C–H functionalization. Mechanistic studies indicate that the (η-benzyl)palladium(II) complex, which is formed...

Bamboo is one of the important biopolymers which is used in chemistry. In this work, for the first time, a solid acid catalyst from bamboo was prepared from the reaction of sawdust bamboo and chlorosulfonic acid. Relevant properties of catalyst were investigated by FT-IR, XRD, SEM and TGA. The sulfonated bamboo (bamboo-SO3H) with several acid functional groups was utilized as highly ...
