摘要：

The preparations of novel thionolactone-bridged configuratively labile biaryls and their [Cp(R3P)2Ru]+-complexes are described. The dynamics of helimerization of these complexes and their reactivity towards nucleophiles have been investigated. Hydride transfer reagents lead to a cleavage of the thionolactone bridge to give the corresponding thiolate complexes, apparently via intermediate exothiolactolate ruthenium complexes. A similar lactolate analog is formed upon addition of a mild S-nucleophile.
