Reactions of a Ditriptycyl-Substituted Selenoseleninate and Related Compounds with a Platinum(0) Complex: Formation of Selenaplatinacycle and Hydrido Selenolato Platinum(II) Complexes

摘要

Oxidative additions of cyclic and acyclic disulfides and their oxides to platinum(0) complexes are a topic of recent research. However, analogous reactions of selenium compounds are limited to diselenides. For example, in the diselenation of terminal acetylenes with diselenides in the presence of palladium(0) and platinum(0) complexes, diselenolato complexes have been proposed as the intermediates. As far as we know, there are no reports on analogous reactions for oxides of diselenides such as seleno-seleninates (RSe(O)SeR), a major reason for which must be that only few isolable selenoseleninates are known. It is important to investigate their reactivity toward low-valent transition-metal complexes and the nature of the resulting selenium metal complexes in relation to the corresponding chemistry of sulfur.
