标题:The Tantalum-Catalyzed Carbozincation Of 1-Alkenes With Zinc Dialkyls
摘要:The Tacl5-Mediated Reaction Between Monosubstituted Alkenes And Et2Zn Affords 3-(R-Substituted)-N-Butylzincs In High Yield (Up To 92%) And Regioselectivity. Organozinc Reagents Bearing A Longer Alkyl Chain (R = Pr-N,Bun,Am-N,Hex(N)) React With 1-Alkenes In The Presence Of Tacl5 As The Catalyst To Give Two Types Of Organozinc Compound Having Iso-Alkyl Structure. The Probable Mechanism Of The Carbozincation Reaction Implies The Formation Of Beta-Substituted And Beta,Beta'-Disubstituted Tantalacyclopentanes As The Key Intermediates. The Thermodynamic Probability Of The Mechanistic Elementary Stages For The Ethylzincation Of Terminal Alkenes Has Been Estimated Using Dft Pbe/sbk Method. (C) 2014 Elsevier B.V. All Rights Reserved.

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:Method for the synthesis of (meth)acrylic esters catalysed by a polyol titanate
发明人：PAUL JEAN-MICHEL
权利人:PAUL JEAN-MICHEL; ARKEMA FRANCE
摘要:The subject of the invention is a method for the synthesis of (meth)acrylic esters by transesterification in the presence of a catalyst corresponding to the formula [(R′O) 3 Ti] x R″ in which R′ is a linear or branched alkyl radical having from 2 to 8 carbon atoms which may contain heteroatoms or R′ is a phenyl radical, R′ is a polyfunctional radical, originating from a polyol R′(OH) x comprising x alcohol functional groups and x is an integer ranging from 2 to 6. The method according to the invention is particularly well suited to the synthesis of dialkylaminoalkyl (meth)acrylates from methyl (meth)acrylate and a dialkylaminoalcohol.
