This
contribution demonstrates that deprotonated amides (amidates)
can be used to stabilize stannylenes. Thus, the dimeric stannylene
[Sn2{μ-tBuNC(O)tBu}2Cl2] (1) was
obtained by treating Li{tBuNC(O)tBu} with 1 equiv of SnCl2. Chloride exchange
reactions of 1 with Li{tBuNC(O)tBu} and Li(HMDS) (HMDS = N(SiMe3)2) lowered aggregation, affording the monomeric tetra-
and tricoordinated tin(II) derivatives [Sn{tBuNC(O)tBu}2] (2) and [Sn{tBuNC(O)tBu}(HMDS)] (3), respectively. Alternatively, 3 can be prepared by direct deprotonation of the amide with
Sn(HMDS)2. Compounds 1–3 are stannylenes that contain an unprecedented SnNCO four-membered
ring.
