reacting a W–W triply-bonded W(III)2 complex, (tBuO)3WW(OtBu)3 (1), with benzo[c]cinnoline derivatives to form biphenyl-linked dinuclear (imido)tungsten complexes 2–4. When azobenzene was used as the substrate, a trans to cisisomerizationinduced by blue-LED light was essential prior to the metathesis cleavage of the NN bond by the WW bond of (Me2N)2(TfO)WW(OTf)(NMe2)2 (6), affording the corresponding
通过使W-W三键结合的W(III)2络合物(t BuO)3 W W(O t Bu)3(1)与苯并苯反应,观察到W W键和N N键的复分解反应。[ c ] cinnoline衍生物形成联苯连接的双核(亚氨基)钨配合物2-4。当使用偶氮苯作为底物时,在(Me 2 N)2(TfO)W的W W键对N N键进行复分解裂之前,由蓝光LED引发的反式至顺式异构化是必不可少的。W(OTf)(NMe 2)2(6),提供相应的亚氨基桥联双核钨配合物7-9。
