概要:
1-Hydroxy-2,3-dimethylindole (1) has been prepared for the first time. Under atmospheric oxygen, 1 was converted rapidly into 3-hydroxy-2,3-dimethyl- 3H-indole N-oxide (2). The structure was deduced, based on its products obtained
…
by the reaction with Ac2O in pyridine and confirmed by X-ray single crystallographic analysis.

eported. First counts were the following 11 taxa : S . amabilis（2n=26）, S . brachyspica（2n=26）, S . in-dica var. parvifolia（2n=26）, S . iyoensis（2n=26）, S . kiusiana（2n=26）, S . laeteviolacea var. laeteviolacea（2n =26）, S . laeteviolacea var. maekawae（2n=26）, S . muramatsui（2n=26）, S . pekinensis var. transitra（2n=28）, S . shikokiana（2n=28）and S . tsusimensis（2n=26）. New counts were reported in S . dependens（2n=28）, S . strigil-losa（2n=30）and S . yezoensis（2n=30）. Chromosome counts for S . barbata（2n=26）, S . guilielmii（2n=28）, S . indica var. indica（2n=26）and S . rubropunctata var. rubropunctata（2n=26）were confirmed.

iamagnetic and paramagnetic compounds and in crystals having a modulated structure. The spectra and T1 of NMR in solids were measured for [M(H2O)6][AB6] crystals to investigate the static and dynamic structure of H2O and [M(H2O)6]2+ as well as the dynamics of the electron spin in the paramagnetic M2+ ion. The physical properties of [M(H2O)6] [AB6] were found to be as follows: (1) The spin-lattice relaxations of the electron spin of M2+ in [M(H2O)6] [SiF6] (M2+ = Fe 2+ , Co2+ , Ni2+) are dominated by the Orbach process, the Orbach process, and the Raman process, respectively. The spin-lattice relaxation of the electron spin of Cu2+ in [Cu(H 2O)6][PtCl6] is caused by jumping between the Jahn-Teller configurations. (2) In [Cu(H2O)6] [PtCl 6], H2O and [Cu(H2O)6]2+ undergo 180° flips and jumping between the different Jahn-Teller configurations, respectively. A weakening of the hydrogen bond O-H⋯Cl upon deuteration results in a lowering of the transition temperature. (3) In [M(H2O)6][SiF6], H2O and [M(H 2O)6]2+ undergo 180° flips and reorientation about the C3, axis, respectively. The order-disorder transition is closely related to a freezing of this reorientation. (4) By elongation of [M(H2O)6]2+ along the C 3 axis, the mobility becomes higher. (5) The disorder of [Fe(H 2O)6]2+ in the high-temperature phase of [Fe(H2O)6][SiF6] is dynamic. Rotational modulation of [Mg(H2O)6]2+ along the C 3 axis exists in the incommensurate phase of [Mg(H2O) 6] [SiF6].

ultrasmall magnetic fields (0.02∼6.21 mT) are investigated experimentally. The simultaneously measured ac susceptibility and static magnetization show neither evidence of the magnetic ordering, superconductivity down to the lowest temperatures nor conventional Landau Fermi-Liquid behavior. The results imply the magnetic transition temperature in undoped CeRu2Si2 is very close to absolute 0 K. The possibility for proximity of CeRu2Si2 to the quantum critical point without any doping is discussed.
