摘要:New ethyl-triazolyl derivatives of the formula (I) in which R represents halogen, X1 represents fluorine, chlorine or bromine, X2 represents fluorine, chlorine or bromine, Z represents halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, ethyl having 1 or 2 carbon atoms and 1 to 5 halogen atoms, halogenoalkoxy having 1 or 2 carbon atoms and 1 to 5 halogen atoms, phenyl, phenoxy, nitro or alkoximinoalkyl having 1 to 4 carbon atoms in the alkoxy moiety and 1 to 4 carbon atoms in the alkyl moiety and m represents the numbers 0, 1, 2 or 3, and addition products thereof with acids or metal salts are very effective for combating fungi. Novel ethyl-triazolyl derivatives of the formula (II) in which R, Z and m have the abovementioned meanings, and addition products thereof with acids or metal salts are very effective for combating fungi. The ethyl-triazolyl derivatives of the formula (II) are also valuable intermediates for the synthesis of ethyl-triazolyl derivatives of the formula (I).

摘要:New heterocyclic hydroxyethyl azoles of the formula in which A represents a nitrogen atom or a CH group, Y represents the groups -CH2-CH2-, -CH = CH- or -C ^ C-, R¹ represents optionally substituted Alkyl, optionally substituted alkenyl, optionally substituted cycloalkyl or for optionally substituted aryl and Het stands for an optionally substituted and optionally benzanellated, five- or six-membered heterocyclic radical having up to 3 heteroatoms, and their acid addition salts and metal salt complexes, processes for the preparation of the new substances and their use as fungicides and plant growth regulators. New alkynols of the formula in which A and R¹ have the meaning given above, processes for their preparation and their use as intermediates for the synthesis of heterocyclic hydroxyethyl azoles of the formula (I).

标 题:Polyalphaolefins made from dimer olefins obtained from branched c10 monoolefins using solid acid catalyst
发明人：MALINSKI THOMAS; GEE JEFFREY C; BISCHOF STEVEN M; KERNS SPENCER A; HILLIER JAMES; WEBSTER-GARDINER MICHAEL S
权利人:CHEVRON PHILLIPS CHEMICAL CO LP
摘要:Synthesis of polyalphaolefins by oligomerization of one or more branched C 10 monoolefins with a solid acid catalyst to form an oligomer product, followed by hydrogenation of a C 20+ olefin portion of the oligomer product to form the polyalphaolefins. The solid acid catalyst is selective to C 20 olefin dimers.

摘要:Straightforvard and inexpensive syntheses of 2-acetyl-1-aza-1-cycloalkenes usefull as bread and rice flavor components, i.e. 2-acetyl-1,4,5,6-tetrahydropyridine and 2-acetyl-1-pyrroline, respectively, comprise the following steps :n oxidation of cyclic amines to cyclic imines; subsequent cyanation of cyclic amines to 2-cyano-1-azacycloalkanes ; oxidation of 2-cyano-1-azacycloalkanes to 2-cyano-1-aza-1-cycloalkenes; synthesis of 2-acetyl-1-aza-1-cycloalkenes by a Grignard reaction. n These syntheses give rise to the title compounds, free of side products, in a way easily amenable to industrial production.
