标题:铁在过氧化氢和高碘酸钠的催化下将不饱和脂肪酸一氧化分解为醛
摘要:通过使用0.5 Mol%的非血红素铁络合物[fe(otf)2(mix-Bpbp)](bpbp = N,N催化剂为'-双(2-吡啶甲基)-2,2'-联吡咯烷),当量为1.5当量的过氧化氢和氧化剂为1当量的高碘酸钠.可以使用手性bpbp配体的非对映异构体的混合物,从而不需要拆分其旋光组分.裂解反应可在20小时内在环境条件下在一个罐中进行.环氧化,酸化和随后的ph中和后加水对于在一锅中进行环氧化,水解和随后的二醇裂解至关重要.可以通过顺式和反式裂解内部脂族双键获得高醛收率构型(86-98%)和不饱和脂肪酸和酯(69-96%).在三取代和末端烯烃的反应中,醛的收率很高(62-63%).可以通过简单的有机溶剂萃取步骤轻松分离出产物.提出的协议涉及比基于ru或os的常规方法更低的催化剂负载量.同样,在这种情况下,过氧化氢也可以用作氧化剂,通常第二,第三排金属不成比例.通过仅使用温和的氧化剂,可以防止醛过度氧化为羧酸.

标 题 :Process for the preparation of an organomercaptophenol from sulfur, a 2,6-disubstituted phenol, and an activated olefin or an epoxy compound
发明人：HAY ALLAN S
权利人:GEN ELECTRIC
摘要:A process for the preparation of an organomercaptophenol is described which comprises the reaction of sulfur with a 2,6-disubstituted phenol carried out in the presence of (1) a base, (2) an activated olefin or an epoxy compound, (3) and a solvent with a high dielectric constant. The organomercaptophenols produced by this process are useful as monomers in the synthesis of esters, carbonates, ethers, epoxy compounds, among many other chemicals synthesized from monohydric phenols. In addition, the oganomercaptophenols are also useful as antioxidants.

标题:Topical administration of catecholamines and related compounds to subcutaneous muscle tissue using percutaneous penetration enhancers
发明人：PERRICONE NICHOLAS V
摘要:Compositions for the topical treatment of sagging subcutaneous muscle and overlying cutaneous tissue contain an active ingredient exhibiting or producing catecholamine activity such as catecholamines and/or related compounds in a dermatologically acceptable carrier that contains at least one percutaneous penetration enhancer. Examplary catecholamines include adrenaline, norepinepherine, dopamine and their precursors; catecholamine precursors such as tyrosine and phenylalanine are preferred. Many embodiments, particularly those employing tyrosine and/or phenylalanine as a catecholamine precursor, further contain a neurotransmitter synthesis enhancer such as dimethylaminoethanol, and other co-factors such as vitamin B 6 and pantothenic acid or calcium pantothenate are included in the composition to enhance the action of the active ingredients. Other compounds that scavenge free radicals and antioxidants may also be added.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
