标题:Enthalpies Of Hydration Of Alkenes. 4. Formation Of Acyclic Tert-Alcohols
摘要:The Enthalpies Of Hydration Of A Series Of Acyclic Alkenes That Lead To Tert-Alcohols Were Determined. Several Pairs Of Alkenes That Give The Same Alcohol Were Studied And Gave The Differences In Enthalpy Of Formation Of The Alkenes. A Consistent Difference In Delta-H(F) Of 1.84 Kcal/mol Was Found Between Di-And Trisubstituted Alkenes. It Was Related To The Difference In Delta-H(F) For Pairs Of Exocyclic And Endocyclic Alkenes. The Enthalpies Of Formation Of The Alcohols Were Obtained And Were Related To Data For Primary And Secondary Alcohols.

权利人:CT ANGEWANDTE NANOTECH CAN
摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

标 题 :Total synthesis of northebaine, normophine, noroxymorphone enantiomers and derivatives via N-Nor intermediates
发明人：RICE KENNER CRALLE; NEWMAN AMY HAUCK
权利人:US HEALTH
摘要:The invention involves a method of making key intermediates useful in the synthesis of many opiate narcotics and antagonists and agonists; and the non-opiate enantiomers thereof which have potent antitussive properties. The synthesis starts from either the natural or unnatural enantiomer of nordihydrocodeinone and produces 8, 14-dihydronorthebaine, the diketal of 7-bromonordihydrocodeinone, northebaine, norcodeinone diketal and 14-hydroxynorcodeinone intermediates without the necessity of leaving the N-nor structure. The syntheses have fewer steps than previous methods, and also have high yields.
