The first thioether elimination reaction utilizing a low-valent titanocene has been discovered. This reaction occurs under mild conditions and affords stereospecifically a variety of dienes and styrenes. Our data suggest that this new reaction involves an intermediate of dimerization of titanocene as the reactant responsible for this elimination.
