已经开发了钯催化的好氧氧化C–H硝化和芳烃与简单易用的亚硝酸叔丁酯(TBN)和甲苯作为自由基前体的酰化反应。分子氧被用作末端氧化剂和氧源以引发活性自由基反应物。在这些新颖的转化中可以使用许多不同的导向基团,例如吡啶,嘧啶,吡唑,吡啶醇,吡啶基酮,肟和偶氮基团。通过自由基过程的Pd II / Pd IV催化循环是这些氧化的CH–H硝化和酰化反应的最可能途径。

electron-withdrawing/-donating substituents for the entire set of compounds reflect a highest occupied molecularorbital (HOMO) character extendedover the metal, the anionic portion of the C∧N ligand, and, in the case of 7−9, the conjugated R group. The reduction potentials indicate that the lowest unoccupied molecularorbital (LUMO) is localized to the C∧N ligand where R = −NO2, and on the dcbpyH2 ligands for all

The production process comprises a step (A) in which an alkali-treated tobacco source is heated to make the tobacco source release a flavoring ingredient into a gas phase, a step (B) in which the flavoring ingredient released into the gas phase is brought into contact with a given solvent which is a liquid substance at ordinary temperature, thereby trapping the flavoring ingredient in the given solvent, and a step (C) in which the given solvent is added to a constituent element.

The present invention provides substituted cyclometalated dyes with wider absorbance bands in the visible spectrum. The compounds have hexacoordinate structures as shown in formula (I) where the central transition metal (M) is bonded to two substituted bipyridine ligands and a cyclometallated 2-phenylpyridine ligand. The R groups are as defined herein. Also provided are a method of manufacturing the dyes and the use of same in electric and photoelectric devices such as dye-sensitized solar cells (DSSC), organic light-emitting diodes (OLED), field effect transistors (FET) and photoelectrochemical (PEC) cells.
