The reaction of allenynes with N2CHSiMe3 in the presence of RuCl(cod)Cp* catalyst at room temperature constitutes a selective, general route to alkylidenebicyclo[3.1.0]hexanes having an adjacent Z-CH=CHSiMe3 group. The reaction shows that the RuCl(Cp*) moiety favours reductive elimination of a metallacyclobutane intermediate and not the enyne metathesis process.
在室温下,使用RuCl(cod)Cp*催化剂,Allenynes与N2CHSiMe3的反应构成了一条选择性高、普适性强的合成具有相邻Z-CH=CHSiMe3基团的烷叉
双环[3.1.0]己烷的途径。该反应表明,RuCl(Cp*)部分倾向于还原消除
