A class of novel ferrocene-triadimenol analogues was synthesized and their biological potential evaluated. Screening data have revealed that these new derivatives did not have antifungal activities of parent compounds, but showed unexpectedly promising plant growth regulatory activity. | |

HLn behaves as a chelating bidentate neutral ligand, bonding through two oxygen atoms. Three fundamental modes of vibrations of the UO22+ ion are IR active in the present polymer complexes which explain the linearity of the uranyl entity. In all complexes, two ligand units and two acetate molecules remain in the equatorial plane. It is also suggested that the two acetate molecules remain in the trans-position. A new relationship between r1,r2,r3 with respect to rt were determined by Global error which shows that the excellent validity is in the sequence: | |
(r3 - rt)2 > Asymmetric oxidation of sulfides catalyzed by chiral (salen)Mn(III) complexes with a pyrrolidine backbone (p 830-834)

Catalytic properties of a series of chiral (pyrrolidinesalen)Mn(III) complexes for asymmetric oxidation of aryl methyl sulfides were evaluated. Moderate activity, good chemical selectivity and low enantioselectivity were attained with iodosylbenzene as a terminal oxidant. The steric effect of the Naza-substituent in the backbone of complexes on the enantioselectivity of sulfide oxidation was explored. | |
Luminescent lanthanide molecular-based hybrid materials bridged through novel urethane linkages (p 835-839)

Novel organosilicates with covalently linked functional modified aromatic acid have been synthesized from 3-aminopropyl triethoxysilane-grafted 4-ethoxy benzoic acid (EB-Si) and terbium ions via a simple low-temperature route. They exhibit effective luminescence and attracting regular micrometer chain microstructure. | |

Selective and controlled aerobic oxidation of activated benzyl alcohols to corresponding aldehydes is achieved in refluxing CH3CN using catalytic amounts of MoO2Cl2(L)2 where L is DMSO, DMF or THF under open air or bubbling of oxygen. Both activated and deactivated varieties of | |

The photochemical reactions of un-substituted alkenes and nitroarenes under CO pressure, catalyzed by [Cp*Fe(CO)2]2, forms the corresponding allyl amines. Trapping experiments suggest that neither aryl nitrene nor nitrosoarene is the active aminating agent in these transformations. | |
Heck reactions of aryl halides with alk-1-en-3-ol derivatives catalysed by a tetraphosphine-palladium complex (p 855-868)

Two novel dithienylethenes with fer-rocene units were synthesized by Wittig reaction. The structure of 2a has been established by X-ray diffraction studies. They could reversibly interconvert between two thermally stable forms, an open and a closed one, using light of different wavelengths as triggers. | |

O2S(tBuN)2PCl reacts with S4N4 to afford 4,6-spirocycle in moderate yield. The deep blue crystals of the spirocycle are air-stable and have high melting point. The 4,6-spirocycle, whose X-ray structure is reported in this paper, is the first example containing a four-membered saturated phosphetidine ring (PN2S) and a six-membered unsaturated | |

Pure perovskite lead titanate powder (PbTiO3) was successfully produced via the sol-gel process using lead and titanium glycolates as starting precursors which had been synthesized by the OOPS process. The product powder calcined at 300 °C for 3 h had the highest dielectric constant and electrical conductivity values: namely, 17470 and 1.83 × 10-3, respectively. | |
