Abstract
AbstractThe reactivity of the chlorostannylene [HC(PPh2=NSiMe3)2SnCl] (2) with various substrates has been investigated. Compound 2 acts as a two‐electron carbene‐like ligand and forms a complex with W(CO)5THF (THF = tetrahydrofuran) to give [HC(PPh2=NSiMe3)2(Cl)Sn→W(CO)5] (4). It reacts with benzil and 3,5‐di‐tert‐butyl‐o‐benzoquinone to give the oxidative cycloaddition products [HC(PPh2=NSiMe3)2(Cl)Sn{O(Ph)C=C(Ph)O}] (5) and [HC(PPh2=NSiMe3)2(Cl)Sn{O(3,5‐di‐tBu‐C6H2)O}] (6), respectively. The metathesis reaction of 2 with excess sodium azide affords [HC(PPh2=NSiMe3)2SnN3] (7). With silver(I) triflate, it forms an ionic triflate salt [HC(PPh2=NSiMe3)2Sn][CF3O2SO] (8), which features an exceptionally long Sn···OSO3CF3 distance. It can act as a ligand‐transfer reagent by reacting with [Fe{N(SiMe3)2}2] to give [HC(PPh2=NSiMe3)2Fe(μ‐Cl)]2 (9). The X‐ray structures of 2–9 have been determined.
