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.
发现了第一个利用低价二茂钛的硫醚消除反应。该反应在温和条件下发生,并立体定向地产生多种二烯和苯乙烯。我们的数据表明,这种新反应涉及二茂钛二聚中间体作为负责这种消除的反应物。
