摘要:The disclosure provides methodology for the synthesis of mono-alkylated cyclopentadiene structures, which can be obtained via fulvene intermediates. In one embodiment, the cyclopentadiene ring is substituted with a trialkylsilyl moiety, which enables the further reaction with certain metal halides to form metal adducts. For example, the monoalkyl cyclopentadienes substituted with a trimethylsilyl group can be reacted with TiCl 4 to provide R*CpTiCl 3 complexes, wherein R* is a group of the formula n nwherein R 1 and R 2 are as defined herein.

标题:Synthesis method for polydimethylketene by friedel-craft cationic polymerization of dimethylketene
发明人：LINEMANN REINHARD; LE GUILLAUME
权利人:ARKEMA FRANCE
摘要:The invention concerns a cationic catalyst system comprising an initiator (I), a catalyst (K) and a cocatalyst (CoK). The cocatalyst (CoK) is an agent releasing the active polymerizing center of its counter anion generated by the reaction between the catalyst (K) and the initiator (I). Said cocatalyst is characterized by the existence of a double bond electron-depleted by an electroattractive group. It is selected, for example, from the group consisting of the following complexing agents including o-chloranyl (3,4,5,6-tetrachloro-1,2-benzoquinone), p-chloranyl (2,3,5,6-tetrachloro-1,4-benzoquinone), nitrobenzene, trinitrobenzene, or tetracyanoethylene.
