Abstract: A process for making methyl esters in high yields is provided. The process comprises contacting aliphatic or aromatic aldehydes and methanol with an iron catalyst, to catalyze the dehydrogenative coupling between aliphatic or aromatic aldehydes and methanol. The reaction is highly selective (<99.9%) toward the formation of methyl esters over homoesters and alcohols and operates at temperatures of less than 100° C. for 2-8 hours.

Abstract: The present invention relates to the synthesis of novel biologically active selenoquinone-derived organometallic complexes, and to the uses thereof in the context of preventing or treating cancer.

Abstract: An object of the present invention is to provide a near infrared absorbent dye capable of providing a near infrared shielding filter with excellent transparency as well as high heat resistance and hygrothermal resistance. The near infrared absorbent dye is characterized in that it is made of the amorphous form of diimmonium salt represented by formula (1).

Abstract: Agents for the diagnosis or treatment of hypoxic cells comprise a bioreductive moiety such as 2-nitroimidazole, and a metal chelating moiety which is a bis-amine oxime of which a carbon atom adjacent a nitrogen atom is linked to the bioreductive moiety. A chelated metal atom or ion preferably Technetium-99m. The agent diffuses into cells where the 2-nitroimidazole is reduced thus trapping the chelated metal in the cell.

Abstract: A novel initiator for photopolymerization is provided, which can polymerize cationically polymerizable organic material by only irradiating at wavelength of 200-500 nm without specific sensitizer and/or post-curing even when it is used at comparatively small amount, whereby the obtained cured product has good physical properties and electric properties.The initiator for photopolymerization of cationically polymerizable organic material according to the present invention comprises a composite obtainable from a reaction between (a) charge transfer complex consisting of biscyclopentadienyl iron derivative and quinoid and (b) at least one salt selected from a group consisting of tetrafluoroborates, hexafluorophosphates and hexafluoroantimonates.

Abstract: Processes for the preparation of tetracyano-1,4-hydroquinone and its conversion to tetracyano-1,4-benzoquinone via a disilver salt are disclosed.
