Syntheses and Structures of Bis(azido)- and Bis(tert-butoxy)cyclodistibazanes
摘要:
Treatment of the dichlorocyclodistibazane [ClSb(mu -N-t-Bu)(2)SbCl] with alkali-metal azides or tert-butoxides afforded trans-[N3Sb(mu -(NBu)-Bu-t)(2)SbN3] and trans-[Bu-l- OSb(mu -(NBu)-Bu-t)(2)(SbOBu)-Bu-t], respectively. These data and other evidence suggest that [ClSb(mu -(NBu)-Bu-t)(2)SbCl], contrary to previous assumptions, is a trans isomer also.[GRAPHICS]

The dichlorocyclodistib(III)azane [ClSb(mu-NtBu)]2 (1) has been shown to exist as the cis isomer in the solid state. A series of bis(1 degree-amino)cyclodistib(III)azanes [R'NHSb(mu-NtBu)]2 (2, R' = tBu; 3, R' = Dipp; 4, R' = Dmp) has been prepared by the reaction of 1 with 2 equiv. of LiNHR'. On the basis of NMR solution spectra, all three derivatives are formed as a mixture of cis and trans isomers

The reaction of (BuNTe)-Bu-t(mu-(NBu)-Bu-t)(2)(TeNBu)-Bu-t with ClSb(mu-(NBu)-Bu-t)(2)SbCl in toluene produces the tricyclic complex [(BuNSb)-Bu-t(mu-(NBu)-Bu-t)(2)(TeNBu)-Bu-t](mu-SbCl)}Cl- (3). In the solid state, the cation in 3 exists as an approximately 3:1 mixture of pyramidal inversion isomers.
