Notes:
The bis[(tert-butyldimethylsilyl)amino]silanes 1-3 are converted into their lithium derivatives 4-7 with BuLi. Depending on the bulkiness of the substituents, the dilithium derivatives 4 and 5 crystallize in cis or trans conformation. Monolithiated 3 (6) forms a four-membered (SiFLiN) ring system, while its dilithium salt is characterized as a lithium silyldiamide (7), Although 4, 5, and 7 have different structures, they react with PF3 (8, 9), SiF4 (10, 11), and CMe3SiF3 (12) as diamides to give the corresponding four-membered ring systems 8-12. The crystal structures of 4 and 5 are reported.
