Zur Reaktivität von intramolekular basenstabilisierten Zinn(II)- Verbindungen mit Mercaptanen,Disulfiden und Peroxiden

Reactivity of Intramolecular Basestabilized Tin(II) Compounds with Mercaptanes, Disulfides, and Peroxides New pentacoordinated stannaocanes can be obtained in good yields by the reaction of intramoleculare basestabilized tin(II) compounds of the typ E(CH₂CH₂S)₂Sn (E = NMe, S) with mercaptanes RSH (R = Ph, PhCH₂) and disulfides RSSR (R = Ph, PhCH₂). The redistributation of the main product proceeds as a byreaction. The resulting spirocompounds and tin tetrathiolates have been determined by ¹¹⁹Sn-n.m.r. spectroscopy. The reaction of the tin(II) compound with dibenzoylperoxide only results in the addition product. All new compounds are characterized by ¹H-, ¹³C- and ¹¹⁹Sn-n.m.r. measurements and partially by i.r. investigations.
