A fluorescent dye, the pyridomethene-BF(2) complex, has been synthesized. Although pyridomethenes did not exhibit fluorescence, complexes exhibited fluorescence both in solution and solid state. The trifluoromethyl-substituted BF(2) complex formed a J-aggregate showed highest quantum yield state among all complexes.
A preliminary study of isopropanol (IPA) adsorption/desorption isotherms on a jungle-gym-type porous coordination polymer, [Zn(2)(bdc)(2)(dabco)](n) (1, H(2)bdc = 1,4-benzenedicarboxylic acid, dabco =1,4-diazabicyclo[2.2.2]octane), showed unambiguous two-step profiles via highly shrunk intermediate framework. The results adsorption measurements 1, using probing gas molecules alcohol (MeOH and EtOH) for the size effect Me(2)CO influence hydrogen bonding, show that are gradual profiles,...
A mixed oxidation-state (Rh24+ and Rh25+) compound, [{Rh2(acam)4}2I]n.6nH2O (Hacam = acetamide), has been synthesized. The compound a nonpenetrating diamondoid arrangement of {Rh2(acam)4} units linked by mu4-iodides. All the dirhodium are crystallographically equivalent, as all iodide atoms. magnetic susceptibility this shows that one-half Rh2 in Rh25+ oxidation state with one odd electron other half closed-shell Rh24+ state. Its electrical conductivity is 1.4 x 10-3 S cm-1 (pellets, room...

One-dimensional (1-D) chain complexes constructed by metal-metal bonds containing three types of metal species-platinum, rhodium, and copper-have been rationally synthesized characterized single-crystal X-ray analyses physical measurements. The paddlewheel or lantern type complex, [Rh2(O2CCH3)4] (i.e., [Rh2]), has a vacant σ* orbital which accepts the electrons from filled dz(2) cis-[Pt(piam)2(NH3)2]·2H2O (1, i.e. [Pt], where piam = pivalamidate) to afford tetranuclear...
Allylic carbonates are cyanated in high yields to β,γ-unsaturated carbonitriles using trimethylsilyl cyanide the presence of a catalytic amount (5 mol %) Pd(PPh3)4 THF under reflux. In reaction, cinnnamyl methyl carbonate affords cinnamyl 98% yield. acetates also provide corresponding carbonitriles, but often lower yields. The cyanations several cis- and trans-alicyclic substrates proceed cleanly (stereoselectivity > 99%) with overall retention. Characterization reaction palladium complexes...
We have succeeded in obtaining unique one-dimensional (1D) chain complexes (1, 2, and 3) comprised of two types metal species: rhodium platinum. These compounds are constructed from a dinuclear complex (i.e., [Rh(2)]) pivalamidate-bridged platinum [Pt(2)]), forming an attractive quasi-1D infinite chain, expressed as -{[Rh(2)]-[Pt(2)]-[Pt(2)]}(n)-. Interestingly, the bridging ligands [Rh(2)] can be varied with trifluoroacetate, acetate, acetamidate groups, indicating possibility electronic...
