Article abstract of DOI:10.1016/0022-328X(94)80213-0

The preparations of novel thionolactone-bridged configuratively labile biaryls and their ⁺-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 ofthe 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.Key words: Ruthenium; Crystal structure; Thionolactone; Ring opening; Fluxionality
