Abstract
Cp2TiCl2-catalyzed cycloboration of methylenecycloalkanes with PhBCl2 in the presence of metallic Mg to obtain a novel spiroboracarbocycles in good yields (70-80%) is reported for the first time. The structure and properties of spiro-fused boriranes were studied using 11B, 1H, 13C NMR spectroscopy and DOSY experiments. 1-Phenyl-substituted boraspiranes are stable in solution at room temperature for a day.
