Abstract

Nucleophilic addition to Sn(II) imido cubanes provides a novel route to heteroleptic stannates, as exemplified by the formation of [{Sn(NHmmp)(O^tBu)₂}K·thf]₂ (2) and [{Sn(MeNCH₂CH₂NMe)(NHmmp)}Li]_∞ (3) from the in situ reactions of the imido Sn(II) cubane [Sn(Nmmp)]₄ (1) (mmp = 2-MeO-6-MeC₆H₃) with ^tBuOK and [MeN(Li)CH₂CH₂(Li)NMe]. This pathway demonstrates that Sn(II) imido cubanes can act as synthons for their aza-stannylene constituents, RN [double bond, length as m-dash] Sn:.
