The reactivity of a C,N‐chelated stannylene L 2 Sn [L = 2‐(Me 2 NCH 2 )C 6 H 4 ] with azobenzene yielded two different products. In the case of reaction in diethyl ether at room temperature, the cyclic complex L 2 Sn–N(Ph)–N(Ph)–SnL 2 was isolated. The second compound, isolated from the reaction in boiling THF, is the product of C–H activation and ortho ‐metallation of azobenzene, the cyclic [2‐(SnL 2 )‐C 6 H 4 ]–N–N–[C 6 H 4 ‐2‐(SnL 2 )]. Byproducts in the second reaction are the free ligand (LH) and the cyclic complex L 2 Sn–(L)Sn–Sn(L) 2 –O(H). (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
