appropriate metal carbonyl complex and subsequent alkylation with triethyloxonium tetrafluoroborate. Monocarbene [MC(OEt)T′T′H}(CO)5], (M = Cr, 1; W, 4), biscarbene [(CO)5MC(OEt)T′T′C(OEt)}M(CO)5], (M = Cr, 2; W, 5), and the products [MC(OEt)T′T′C(O)OEt} (CO)5], (M = Cr, 3; W, 6), where a metal moiety of 2 and 5 has been replaced by an ester functionality, were isolated. The reaction product afforded
使用经典的 Fischer 方法制备了具有 3,6-二甲基噻吩并 [3,2-b] 噻吩 (T'T') 和噻吩并 [3,2-b] 噻吩 (TT) 间隔基的双核卡宾配合物。研究了它们在溶液中对氧的反应性以及它们的结构特征。铬和钨卡宾配合物是通过噻吩并噻吩的二锂化合成的,然后加入适当的金属羰基配合物,然后用四氟硼酸三乙基氧鎓进行烷基化。单卡宾 [MC(OEt)T'T'H}(CO)5], (M = Cr, 1; W, 4), 双卡宾 [(CO)5MC(OEt)T'T'C(OEt) )}M(CO)5], (M = Cr, 2; W, 5), 以及乘积 [MC(OEt)T'T'C(O)OEt} (CO)5], (M = Cr, 3; W, 6),其中 2 和 5 的金属部分已被酯官能团取代,被分离出来。Cr(CO)6 与锂化噻吩[3,
