Titanocene(III) chloride reacts with glycosyl halides and with epoxides to generate carbon-centered radicals. The primary reaction of these radicals is combination with another molecule of Cp2TiCl. These radicals also can abstract hydrogen atoms from the solvent or other hydrogen-atom transfers in the reaction mixture or undergo radical addition and cyclization reactions. If a radical combines with a second molecule of titanocene(III) chloride, the resulting organotitanium compound typically undergoes a β-elimination reaction. The result of such a reaction usually is formation of a glycal.
