Syntheses and C-H bond activation reactions of the novel electrophilic PtII complexes [(tmeda)Pt(CH3)(OEt2)][BAr1], [(tmeda)Pt(CH3)(THF)][BArf], and [(tmeda)Pt(CH3)(NC5F5)][BArf] are described {[BArf]− = [(3,5-C6H3(CF3)2)4B]−} (tmeda is N,N,N′,N′-tetramethylethylenediamine), [(tmeda)Pt(CH3)(OEt2)][BArf] and [(tmeda)Pt(CH3)(THF)][BArf] are unstable at room temperature, yielding methane and the Fischer carbene PtII hydrides, [(tmeda)Pt(=C(CH3)(OCH2CH3))(H)][BArf] and . The methane liberated from [(tmeda)Pt(CH3)(OEt2-d10)][BArf] consists of an isotopomeric mixture, (CH4, CH3D, CH2D2 and CHD3), indicating a multiple H/D exchange reaction following the C-D activation and prior to methane loss. [(tmeda)Pt(CH3)(THF-d8)][BAr] liberates CH4 and CH3D. Methane-13C, cyclohexane, toluene, and benzene react with [(tmeda)Pt(CH3)(NC5F5)][BArf] to yield methane and new organoplatinum complexes. Deuterated alkanes and arenes react with [(tmeda)Pt(CH3)(NC5F5] [BArf] to give a mixture of methane isotopomers. The relevance of these results to the oxidation of alkanes by aqueous platinum complexes is discussed. 相似文献

Simian cytomegalovirus infections were studied in captive, naturally infected primates and in experimentally infected rhesus monkeys. Neutralizing antibody to simian cytomegalovirus was prevalent in selected species of Old World Monkeys. Naturally infected, rhesus monkeys shed virus in their urine during the entire two-year period of study. Similarly, experimentally infected rhesus monkeys showed neutralizing antibody and viruria for more than two years. The indirect fluorescent antibody procedure was found more sensitive than the neutralization antibody technique but appeared less specific for antibody to cytomegalovirus strains. 相似文献
