The reactivity of a C,N-chelated stannylene L2Sn [L = 2-(Me2NCH2)C6H4] with azobenzene yielded two different products. In the case of reaction in diethyl ether at room temperature, the cyclic complex L2Sn–N(Ph)–N(Ph)–SnL2 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-(SnL2)-C6H4]–N–N–[C6H4-2-(SnL2)]
C,N-螯合的亚锡基 L2Sn [L = 2-(Me2NCH2)C6H4] 与偶氮苯的反应产生两种不同的产物。在室温下在乙醚中反应的情况下,分离出环状络合物 L2Sn-N(Ph)-N(Ph)-SnL2。从沸腾的四氢呋喃反应中分离出的第二种化合物是偶氮苯的 C-H 活化和邻位金属化的产物,即环状 [2-(SnL2)-C6H4]-N-N-[C6H4-2-(SnL2 )]。第二个反应中的副产物是游离配体 (LH) 和环状复合物 L2Sn–(L)Sn–Sn(L)2–O(H)。(© Wiley-VCH Verlag GmbH & Co.
