标题:High Temperature Pyrolysis Of 1,5-Cyclooctadiene And 4-Vinylcyclohexene In Shock Waves
摘要:Abstract1,5‐cyclooctadiene Or 4‐vinylcyclohexene Mixture Diluted With Argon Was Heated To Temperatures In The Range 880-1230 K Behind Reflected Shock Waves. Profiles Of Ir‐laser Absorption Were Measured At 3.39 μm. From These Profiles,Rate Constants K1 And K2 For The Decyclization Reactions 1,5‐cyclooctadiene-> Biradical And 4‐vinylcyclohexene-> Biradical Were Evaluated As K1 = 5.2 x 1014 Exp(−48.3 Kcal/rt) S−1 And K2 = 3.5 x 1014 Exp(−55.3 Kcal/rt) S−1,Respectively. © 1993 John Wiley & Sons,Inc.

摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

权利人:UNIV WATERLOO
摘要:A process for the synthesis of arborescent polymers comprises epoxidation of a first polymer and grafting thereto a second polymer having groups reactive to the epoxide groups on the first polymer. The epoxidation and grafting steps can be repeated. In an additional embodiment, the present invention provides a one-pot method for the synthesis of arborescent polymers. In a reaction pot, a first polymer is copolymerized and then reacted with an activating compound in order to generate a polyfunctional macroinitiator. Monomers are then added to the reaction pot, the monomers having functional groups reactive towards reactive sites on the first polymer.

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.
