selectively with Fe2(CO)9 to afford monoiron tricarbonyl and diiron hexacarbonyl complexes with retention of the heteroatomic chain. Oxidative decomplexation demonstrates the reversibility, with no loss of sulphur, of the reaction. In the case of the thiaazadiene bearing a thioalkyl group in position 2 (R2 = C6H5CH2S), complexation with Fe2(CO)9 involves the sulphur atom, to give a major product with a metallocarbene
1-硫杂-3-氮杂-丁二烯- [R 2 C(S)NC(CO 2 C ^ 2 ^ h 5)N(CH 3)2轴承的芳香族取代基R 2在位置2(R 2 = C 6 H ^ 5) ,与Fe 2(CO)9选择性反应,得到具有杂原子链保留的单铁三羰基和二铁六羰基配合物。氧化分解表明反应是可逆的,没有硫的损失。在噻唑二烯在位置2带有硫代烷基的情况下(R 2 = C 6 H 5 CH 2S),与Fe 2(CO)9的络合涉及硫原子,得到具有金属碳烯结构的主要产物。13 C NMR和红外光谱数据与通过X射线衍射法测定的配合物的结构一致。
