Thionyl tetrafluoride gas reacts efficiently with primary amines to form reactive iminosulfur oxydifluoride compounds. These dual SVI-F loaded iminosulfur oxydifluoride compounds, in turn, readily react with secondary amines or aryloxy silyl ethers (ArO-SiR3), yielding the corresponding fused heteroatom-linked substrates. Iminosulfur oxyfluoride polymers also are provided by disclosed methods.

Sulfur(VI) fluorideexchange (SuFEx) is a new family of click chemistry based transformations that enable the synthesis of covalently linked modules via SVI hubs. Here we report thionyl tetrafluoride (SOF4) as the first multidimensional SuFEx connector. SOF4 sits between the commercially mass‐produced gases SF6 and SO2F2, and like them, is readily synthesized on scale. Under SuFEx catalysis conditions

used to introduce oxygen substituents into (η-arene)(η-cyclopentadienyl) iron (II) complexes. Photochemical ligand exchange led to the formation of the first recorded trioxygenated complex as well as mono- and di-oxygenated species. Using microwave techniques, reaction times for SNAr displacement reactions of halobenzene complexes by phenols were reduced from several hours to a few minutes. Phenols protected
已使用一系列反应将氧取代基引入(η-芳烃)(η-环戊二烯基)铁(II)络合物中。光化学配体交换导致形成第一个记录的三加氧配合物以及单加氧和双加氧物质。使用微波技术,通过苯酚进行卤代苯配合物的S N Ar置换反应的反应时间从数小时减少至数分钟。苯酚受任一t保护使用常规的热配体交换反应,发现-丁基化或三甲基甲硅烷基化产生适量的相应酚配合物。没有这种保护,收率极低。上述方法导致二羟基苯配合物的第一实例的合成。还报告了一些其他合成方法。

of L5–8 has been explored with Mo(0), Pt(0) and Rh(I) and it is shown that the π-acceptor properties of L5–8 increase with decreasing ring size. The IR spectra and X-ray crystal structures of the [Mo(CO)4L2] complexes show that L5–8 lie between PF3 and P(OAr)3 in terms of their σ/π-bonding properties. The [PtL4] complexes are readily prepared from [Pt(nbe)3] and 4 equiv. of L5–8 whereas equilibrium mixtures
