✦ Synopsis


Starting from 1,3-di-tert-butyl-2,4-dichloro-l,3,2,4-diazadistibetidine a series of 1,3,2,4-diazadistibetidines [R -SbN -tBuI2 with R = OMe (2), OPh (3), OtBu (4), N(Tms)2 (5), P(Tms), (6), Me (7), and tBu (8) has been synthesized. The NMR spectra prove most of the reaction products to be mixtures of geometrical isomers. The structure of trans-tetra-tert-butyldiaza- distibetidine 8a was confirmed by X-ray structure deterrnination.

Zur Frage der geometrischen Isomerie bei substituierten Diazadiphosphetidinen wurden in den letzten Jahren zahlreiche Untersuchungen durchgefuhrt ' 3 ' ) .
