标题 :Method for the production of monomers useful in the manufacture of semiconductive polymers

权利人:MERCK PATENT GMBH
摘要:The instant invention relates to a new method for the synthesis of monomers and their use inter alia in the manufacture of semiconductive polymers. Monomers, in particular, asymmetric monomers, such as asymmetric fluorene compounds, are valuable material in the manufacture of semiconductive polymers. The know methods for producing asymmetric monomers, such as asymmetric fluorene compounds, are expensive due to the formation of by-products. n The method according to the present invention avoids the formation of such by-products and is described in more detail in claims 1 to 14.

标 题:Soluble highly reactive form of calcium and reagents thereof
发明人：RIEKE REUBEN D
权利人:UNIV NEBRASKA
摘要:A soluble highly reactive form of calcium, prepared from Ca(II) salts and a reducing agent in ethereal, polyethereal, or hydrocarbon solvents, is presented. This form of calcium can be used in the preparation of organocalcium reagents. The organocalcium reagents resulting from the reaction of the soluble highly reactive calcium with organic compounds containing either halide, cyanide, a 1,3-diene, or a polyunsaturated functionality, are stable, useful reagents for organic synthesis. The organocalcium halide reagents undergo Grignard-type reactions. They also undergo reactions with Cu(I) salts to form organocalcium cuprate reagents. The organocalcium cuprate reagents undergo a variety of cross-coupling reactions. The soluble highly reactive calcium reacts with 1,3-dienes to yield the corresponding 2-butene-1,4-diylcalcium complexes. These bis-organocalcium reagents can undergo dialkylation reactions with α,ω-alkylene dihalides and dichlorosilanes to form the corresponding 3-, 5-, and 6-membered ring derivatives. The soluble highly reactive calcium also reacts with organic dihalides to form mono- or diorganocalcium compounds which can be converted into a wide variety of polymers.
