摘要：

The reaction of methylidenecycloalkanes with BF3 center dot 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- (H-1, C-13 DEPT, B-11, F-19) and two-dimensional (COSY, HSQC, HMBC) NMR and mass spectra in combination with quantum chemical calculation of C-13 chemical shifts.
