Kinetic Stabilization in Diaryl-Substituted Stannylenes: N2O Reactivity, Intramolecular C–H Activation, and Crystalline (Eind)Li(THF)2 as a Versatile Precursor in Tin Chemistry
The reactivity of the kinetically stabilized stannylene (MesTer)2Sn (1) (MesTer = –C6H3-2,6-(2,4,6-Me3-C6H2)2) toward N2O is revisited, yielding the terminal tin(IV) hydroxide 2 via formal intramolecular C(sp3)–H activation of a putative terminal stannanone intermediate. By switching to Eind ligation (Eind = 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl) at the tin center, the synthesis and characterization of the crystalline lithium salt (Eind)Li(THF)2 (3) is reported, serving as a straightforward precursor for the clean generation of the corresponding stannylene (Eind)2Sn (4). Compound 4 can be further cleanly converted into the heteroleptic Eind/halide stannylene (Eind)SnCl (6). Both 4 and 6 serve as suitable precursors for the synthesis of the heteroleptic s-hydrindacene-/amido-substituted stannylene (Eind)Sn{N(SiMe3)2} (5).
