标 题:Synthesis of glycols via transfer hydrogenation of alpha-functional esters with alcohols
发明人：CHAKRABORTY SUMIT; HEMBRE ROBERT THOMAS
权利人:EASTMAN CHEM CO
摘要:A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H 2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H 2 . The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.

标题:Process for the preparation of acyl cyanide compounds
发明人：FINDEISEN KURT; KRAETZER HANS; LENTHE MANFRED
权利人:BAYER AG
摘要:This invention relates to a new process for the preparation of acyl cyanides of the general formula n n R.sup.1 --CO--CN (I) n n wherein R 1 is an optionally substituted alkyl radical up to 18 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5- or 6-membered heterocyclic radical, which can additionally also be fused with a benzene ring, which process comprises reacting a carboxylic acid anhydride of the formula n n R.sup.1 --CO--O--CO--R.sup.1 (II) n n with an alpha-hydroxynitrile of the formula ##STR1## in which R 2 and R 3 are identical or different and represent a hydrogen atom, an optionally substituted alkyl radical with 1 to 18 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5- or 6-membered heterocyclic radical, which can additionally also be fused with a benzene ring. The acyl cyanides (I) are known compounds and can be used as starting material for the synthesis of herbicides.

标题 :Process for the preparation of acyl cyanides
发明人：KLAUKE ERICH; FINDEISEN KURT
权利人:BAYER AG
摘要:A novel process for the preparation of acyl cyanides of the general formula R-CO-CN (I) wherein R represents an optionally substituted alkyl radical with 1 to 8 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5-membered or 6-membered heterocyclic radical, which can additionally be fused to a benzene ring, in which a carboxylic acid fluoride or the general formula R-CO-F (II) in which R has the abovementioned meaning is reacted with an alkali metal cyanide, optionally in the presence of a diluent, at a temperature between 10 DEG and 200 DEG C. The acylcyanides (I) can be used as intermediates in the synthesis of known herbicides.

标 题 :Synthesis of ethyl bromopyruvate
发明人：LAPIN YURI A; REINEKE KARL E; KUNNEN KEVIN B; SANCHEZ IGNACIO H
权利人:GREAT LAKES CHEMICAL CORP
摘要:A process to manufacture ethyl bromopyruvate from ethyl pyruvate by reacting ethyl pyruvate with bromine chloride. The reaction may be carried out by contacting ethyl pyruvate with pre-formed bromine chloride or with bromine chloride generated in situ. Subsequent purification of the crude product mixture produces ethyl bromopyruvate in high purity.
