Summary in another language: |
Pentacarbonyl(thietane)tungsten complexes react with thiocyanate, [SCN)", and Si02/H20 by insertion ofthe CN group mto a S-C bond ofthe four-membered heterocycIe, 1,3-migration of the pentacarbonyltungsten fragment and protonation of the nitrogen atom to give tungsten-coordinated thiazmtione complexes. Analogously, the reactions of a thietane tungsten complex wIth [SeCN]" and Si02/H20 affords a thiazinselone complex. A selenazinthione complex is obtained from a se~enetane complex and [SCN)" (+ SiOz/HP). The insertions are regiospecific and stereoselechve. The structure of the trans-isomer of a pentacarbonyl(thiazinthione) complex has been established by X-ray structure analysis.
