Carbon-hydrogen bond breaking and making in the open-shell singlet molecule Cp2Yb(4,7-Me2phen)

The adducts formed between the 4,7-Me2-, 3,4,7,8-Me4-, and 3,4,5,6,7,8-Me6-phenanthroline ligands and Cp2Yb are shown to have open-shell singlet ground states by magnetic susceptibility and LIII-edge XANES spectroscopy. Variable-temperature XANES data show that two singlet states are occupied in each adduct that are fit to a Boltzmann distribution for which δH = 5.75 kJ mol-1 for the 4,7-Me2phen adduct. The results of a CASSCF calculation for the 4,7-Me2phen adduct indicates that three open-shell singlet states, SS1-SS3, lie 0.44, 0.06. and 0.02 eV, respectively, below the triplet state. These results are in dramatic contrast to those acquired for the phenanthroline and 5,6-Me2phen adducts, which are ground state triplets (J. Am. Chem. Soc. 2014, 136, 8626). A model that accounts for these differences is traced to the relative energies of the LUMO and LUMO+1 orbitals that depend on the position the methyl group occupies in the phenanthroline ligand. The model also accounts for the difference in reactivities of Cp2Yb(3,8-Me2phen) and Cp2Yb(4,7-Me2phen); the former forms a σ C-C bond between C(4)C(4′), and the latter undergoes C-H bond cleavage at the methyl group on C(4) and leads to two products that cocrystallize: Cp2Yb(4-(CH2),7-Mephen), which has lost a hydrogen atom, and Cp2Yb(4,7-Me2-4H-phen), which has gained a hydrogen atom.

Color responses of novel receptors for AcO- and a test paper for AcO- in pure aqueous solution

An efficient AcO- sensor L which contains 1,10-phenanthroline-based and nitrophenylhydrazine-based groups, and its water-soluble Ru(II) complex were synthesized, characterized and studied in this Letter. Via UV-vis experiments and 1H NMR titration in DMSO solution, it was found that there were potential hydrogen bonds between the N{double bond, long}CH and AcO- after the deprotanation of two -NH during the reaction of L or its Ru complex with anions. Furthermore, an easy-to-prepare test paper was developed to detect AcO- at 10 mg/L in pure aqueous solution.
