Darstellung, Struktur und Stereoisomerie von 1,3‐Di‐tert‐butyl‐1,3,2,4‐diazadistibetidinen

Synthesis, Structure, and Stereoisomerism of 1,3‐Di‐tert‐butyl‐l,3,2,4‐diazadistibetidines Starting from 1,3‐di‐tert‐butyl‐2,4‐dichloro‐1,3,2,4‐diazadistibetidine a series of 1,3,2,4‐diazadistibetidines [R–SbN–ttBu]2 with R = OMe (2), OPh (3), OtBu (4), N(Tms)2 (5), P(Tms)2 (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 determination.
