标题:硫从1,2,4-二噻唑烷-3,5-二酮向三苯膦转移的机理
摘要:研究了在25oc下用4-(3-和4-取代)-1,2,4-二噻唑烷-3,5-二酮在乙腈,二氯甲烷,四氢呋喃和甲苯中取代的三苯基膦的硫化机理.反应途径包括限制磷对硫的最初亲核进攻,然后将intermediate中间体快速分解为相应的膦硫化物,苯基异氰酸酯和羰基硫化物.从哈米特相关性和对溶剂的依赖性,可以得出结论,过渡态结构是非常极性的,类似于两性离子中间体.在溶剂系列中,Ps键形成和ss键断裂的程度非常相似,但是随着溶剂极性的降低,后者逐渐降低.版权所有©2013 John Wiley&sons,Ltd.

标题:Synthesis of isocyanates from nitroalkanes
发明人：MILLIGAN BARTON; PINSCHMIDT JR ROBERT K
权利人:AIR PROD & CHEM
摘要:A process for the preparation of aromatic isocyanates from nitroalkanes. A nitromethyl aromatic compound of the general formula: wherein R and R1 represent hydrogen, halogen, a C1-C5 alkyl radical, a C1-C4 alkoxy radical, nitro, isocyanato, an alkoxycarbonylamino, or nitromethyl radical, with R and R1 being the same or different, is heated in the presence of an effective amount of a Lewis acid or Bronsted acid substance to effect a dehydrogenation-isomerization reaction to yield an aromatic isocyanate of the general formula: The product of the reaction may be recovered as the aromatic isocyanate or the alcohol adduct, a carbamate.

标题 :Polyfluoroalkylthio alcohols, esters and useful compositions therefrom
发明人：DEAR ROBERT E A; BRACE NEAL O
权利人:CIBA GEIGY CORP
摘要:Polyfluoroalkylthio alcohols and esters thereof are disclosed with utility as intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. The novel alcohols and esters are obtained by a free radical catalyzed addition of polyfluoroalkylthiols to acetylenic alcohols or esters thereof. The alcohols are employed in preparation of fluorine containing polyurethanes which are useful as finishes to provide oil and water repellency to textiles and as additives to plastics to provide mold release and other desirable properties.

发明人：DEAR ROBERT ERNEST ARTHUR; FALK ROBERT ALLAN
权利人:CIBA GEIGY CORP
摘要:Perfluoroalkylthio glycols and esters thereof can be prepared by the free-radical catalyzed addition of a perfluoroalkylthiol to an acetylenic alcohol or ester thereof. The compounds obtained are useful intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. In one embodiment, a perfluoroalkylthio glycol can be reacted with a diisocyanate to obtain a polyurethane containing perfluoroalkylthio groups, which polyurethanes are useful as coatings to provide oil and water repellence to textiles and as additives to plastics to provide mold-release and other desirable properties.
