Abstract The reaction of methylidenecycloalkanes with BF3·THF in the presence of Cp2TiCl2 as catalyst has been performed for the first time to obtain 1-fluoroboriranes spiro-fused to cycloalkanes and 1-methylcycloalk-1-enes formed as a result of isomerization of the initial olefin. The product structure was confirmed by one- (1H, 13C DEPT, 11B, 19F) and two-dimensional (COSY, HSQC, HMBC) NMR and mass
摘要 首次在Cp 2 TiCl 2催化剂存在下亚甲基环烷烃与BF 3 ·THF反应得到环烷烃螺稠合的1-氟硼烷和异构化形成的1-甲基环烷-1-烯的初始烯烃。通过一维( 1 H, 13 C DEPT, 11 B, 19 F)和二维(COSY, HSQC, HMBC) NMR和质谱结合13 C化学位移的量子化学计算确定了产物结构。
