Über die Umsetzung von Natriumselenid mit Triphenylchlorstannan und Dimethyldichlorstannan

Abstract

Aus Natriumselenid und Triphenylchlorstannan wird neben Natriumchlorid in sehr guten Ausbeuten Bis‐triphenylzinn‐selenid gebildet. Die Umsetzung von Dimethyldichlorstannan mit Natriumselenid führt zum ringförmigen trimeren Dimethylzinnselenid.

Synthesis, Crystal Structures and NMR Characterization of Molecular Silver Tin Chalcogenide Complexes

“…While (Ph 2 SnO) 3 is commercially available, (Me 2 SnO) 3 and ( t Bu 2 SnO) 3 were synthesized starting from Me 2 SnCl 2 and t Bu 2 SnCl 2 (obtained by reaction of SnCl 4 with t BuMgCl [36] ) in aqueous NH 3 [37] . (Me 3 Si) 2 E (E=S, Se) was prepared by reaction of Na 2 E (obtained by the reaction of the elements in liquid NH 3 [38] ) and Me 3 SiCl [39] . Zn( edt ) ( edt 2− = − SC 2 H 4 S − ) as co‐thermolysis agent was prepared from ZnEt 2 and HSC 2 H 4 SH in n ‐pentane.…”
