摘要:我们在下面介绍一种磺化-聚乙二醇涂层的fe 3 O 4纳米复合材料(fe 3 O 4 / Peg-So 3 H),它是一种非常有效的生态纳米催化剂,用于在溶剂中将硫化物选择性氧化为亚砜或砜,并具有出色的收率.游离条件,采用30%的过氧化氢作为氧化剂.在不改变所需特性的情况下,许多含有醇,酯和醛官能团的硫化物被有效地和选择性地氧化.磁性纳米催化剂(fe 3 O 4 / Peg-So 3H)可以通过使用外部磁性工具方便快捷地回收,并循环使用10多次以上,而不会显着降低其催化性能.

标题:One-step synthesis of alpha, beta-unsaturated sulfonate salts by the reaction of carbon tetrahalides with certain sulfones
发明人：MEYERS CAL Y; HO LAURENCE L
权利人:UNIV SOUTHERN ILLINOIS
摘要:.alpha.,.beta.-Unsaturated sulfonic acid salts are prepared by a one step synthesis involving reaction of a di-primary alkyl sulfone, an arylmethyl primary alkyl sulfone, an .alpha.-halo diprimary alkyl sulfone, or an .alpha.-haloarylmethyl primary alkyl sulfone with a carbon tetrahalide and a strong base. The sulfone substrate is reacted with a carbon tetrahalide represented by the formula CBr.sub.m Cl.sub.n F.sub.p where m and n are integers between 0 and 4 inclusive, p is an integer between 0 and 2 inclusive and m+n+p = 4 in the presence of the strong base to form a geminally .alpha.-dihalogenated intermediate and dihalocarbene. The geminally .beta.-dihalogenated intermediate reacts rapidly in situ with the strong base to form an .alpha.,.beta.-unsaturated sulfonic acid salt and a halide salt. The unsaturated sulfonic acid salt may be acidified to form the corresponding acid or reacted with a halogenating agent to form the corresponding acid halide. .alpha.,.beta.-Unsaturated sulfonic acid salts are useful detergents.

标题:Solid phase synthesis of novel biaryl triazine library by suzuki cross coupling
发明人：CHANG YOUNG-TAE

摘要:Two methods are used to produce diaryl trisubstituted triazines. In the first method, cyanuric chloride is first reacted with a 4-alkoxybenzylamine. The product of this reaction is then reacted with a resin-bound amine, such as 4-alkoxybenzylamine, to ensure that the final compound will be bound to a resin. The product of this reaction is then reacted with boronic acid to produce a trisubstituted diaryl triazine. In the second method, cyanuric chloride is reacted with a benzenealkanethiol. The product of this reaction is then reacted with a resin-bound amine, such as 4-alkoxybenzylamine, to ensure that the final compound will be bound to a resin. The product of this reaction is then reacted with m-CPBA to form a sulfone, which is then reacted with a 4-alkoxybenzylamine to form the desired trisubstituted biaryltriazine.

标题:Chemical synthesis optimiser
发明人：CRONIN LEROY
权利人:UNIV GLASGOW COURT
摘要:The present invention relates to a method of optimising an instruction set for a chemical synthesis and a chemical synthesiser for use in a method of optimising an instruction set for a chemical synthesis. The method comprises (i) performing a chemical synthesis in a reaction vessel of a chemical synthesiser operating according to an instruction set to produce a reaction product, (ii) recording reaction data using an analytical unit of the synthesiser during the chemical synthesis and/or recording product data on the reaction product, (iii) analysing the reaction data and/or product data using a control unit of the chemical synthesiser to determine a characteristic of the synthesis; and (iv) adjusting one or more reaction parameters of the instruction set, to provide an adjusted instruction set, based on a prediction that the adjustment will improve the characteristic of the synthesis.

标题 :Branched siloxanes and methods for synthesis
发明人：WILLSON C GRANT; OGAWA TSUYOSHI; JACOBSSON MICHAEL B
权利人:UNIV TEXAS
摘要:The present invention describes branched and functionalized siloxanes and methods for making such compounds. The compounds have a variety of uses. One preferred application is as novel planarizing material for lithogaphy, in which case functionalized branched siloxane, such as an epoxy-modified branched siloxane is particularly useful.
