Abstract: The invention relates to a method for producing alkaline amides or imides of ethylenically unsaturated C3 to C6 carboxylic acids by reacting amines that contain at least one primary and/or secondary amino group and at least one tertiary amino group with ethylenically unsaturated C3 to C6 carboxlic acids to form an ammonium salt and said ammonium salt is subsequently converted into the alkaline amide or imide by means of microwave radiation, with the proviso that the primary and/or secondary amino group is devoid of alkoxy groups.

Abstract: The present invention is directed to a method for making an enantiomeric organic compound having a high amount of enantiomer excesses including the steps of a) providing an aqueous solution including an initial reactant and a catalyst; and b) subjecting said aqueous solution simultaneously to a magnetic field and photolysis radiation such that said photolysis radiation produces light rays that run substantially parallel or anti-parallel to the magnetic field passing through said aqueous solution, wherein said catalyst reacts with said initial reactant to form the enantiomeric organic compound having a high amount of enantiomer excesses.

Abstract: A method and a device for producing and storing electrical energy using iron complexes, using an iron +III molecular complex as well as a photoreduced iron +II complex, both complexed chemically by a ligand of the benzoic hydrazide type.
Abstract: Methods and reagents for photo-initiated carbonylation with carbon-isotope labeled carbon monoxide using amines and alkyl/aryl iodides are provided. The resultant carbon-isotope labeled amides are useful as radiopharmaceuticals, especially for use in Positron Emission Tomography (PET). Associated kits for PET studies are also provided.

Abstract: A method of transferring electrons with a light energy conversion material is described. The material includes a silica porous material having silicon atoms chemically bonded with an organic group that is an electron donor in a skeleton thereof, and an electron acceptor disposed in at least one portion among a pore, the skeleton and the outer circumference of the porous material. The method includes absorbing light energy by the organic group and transferring electrons excited by the light energy to the electron acceptor.

Abstract: The invention provides a process for producing a fluorine-containing compound from an inexpensive material. Namely, Compound I such as RACH2OH is reacted with Compound II such as XCORB to form Compound III such as RACH2OCORB, followed by fluorination in a liquid phase to form Compound IV such as RAFCF2OCORBF, which is converted to Compound V such as RAFCOF and/or Compound VI such as RBFCOF. RA is an alkyl group or the like, RB is a perhalogenoalkyl group or the like, RAF and RBF are fluorinated RA and RB, and X is halogen.
Abstract: The present invention refers to a process for the preparation of 2-bromomethyl-6-methyl-benzoic acid (I) and derivatives thereof by selective bromination of 2,6-dimethylbenzoic acid (II) with sodium bromate and hydrobromic acid in the presence of light.
