It is also possible to carry out the Kulinkovich reaction in the presence of an additional alkene and together with an ester this leads to the formation of a cyclopropanol incorporating substituents from both of these reactants. However, the choice of the alkene component is critical in order to ensure that the ligand-exchange reaction provides the desired alkene–titanium complex efficiently. In this respect, both styrenes[81,90] and vinylsilanes[91] may be successfully employed (Table 10).
