with [Fe2(CO)9] to afford the bis-μ-(S-alkyl)hexacarbonyldiiron coordination compounds: I (R1 = R2), II (R1R2 = bridging hydrocarbon chain) and III (R1 ≠ R2) after a double fragmentation pattern accompanied by loss of carbonyl groups. This unexpected reactivity of ligands IV offers a general route to binuclear iron compounds such as I and II. Some reaction intermediates [μ(RS)-μ-(RSCO)-Fe2(CO)6] (V)
二硫代碳酸酯R 1 SC(O)SR 2(IV)与[Fe 2(CO)9 ]反应,得到双μ-(S-烷基)六羰基二铁配位化合物:I(R 1 = R 2),II(R 1 R 2 =桥接烃链)和III(R 1 ≠R 2)经过双断裂模式并伴有羰基的丢失。配体IV的这种出乎意料的反应性提供了通向双核铁化合物(例如I和II)的一般途径。一些反应中间体[μ(RS)-μ-(RSCO)-Fe 2(CO)6](V)导致I,被识别。然而,在IV(R 1 ≠R 2)络合过程中发生的S-烷基基团的重新分布表明脱羰反应可以遵循几种途径。
