  New 1,2-disubstituted ferrocenes [5(b–j), in which R = –SMe, –SPh, –SiPr, –SiMe3, –SePh, –SnBu3, –B(OH)2, –Me, –I] with a thiazoline ring in the ferrocene backbone using as key intermediate a ferrocenyl Fischer carbene complex were synthesized. The capability of the 2-thiazoline moiety as an ortho-directed metalation group was demonstrated by subsequent quenching of lithium intermediate with several electrophiles, proving to be an excellent method for synthesizing bidentate ligands. The catalytic scope of the [N,S] ligand 5b as the corresponding palladium complex 5b-PdCl222 in a microwave-promoted Heck reaction was also tested. Results obtained showed better catalytic activity of 5b-PdCl222 compared to other catalytic systems based on a [N,S] ferrocenyl ligand.

  合成了一系列新的1,2-二取代的铁烯 [5(b–j)，其中R = –SMe, –SPh, –SiPr, –SiMe3, –SePh, –SnBu3, –B(OH)2, –Me, –I]，这些化合物在铁烯骨架中带有噻唑啉环，并以铁烯菲舍尔卡宾复合物作为关键中间体。通过将锂中间体与几种电亲体的后续反应，证明了2-噻唑啉基作为邻位定向金属化基团的能力，这成为合成双齿配体的一个优良方法。此外，还测试了[N,S]配体5b作为相应的钯复合物5b-PdCl222在微波促进的赫克反应中的催化范围。结果显示，5b-PdCl222的催化活性优于其他基于[N,S]铁烯配体的催化系统。

  with 4‐amino‐5‐methyl‐4‐H‐1,2,4‐triazole‐3‐thiol (4‐AMTT) as a ligand. This magnetite nanocatalyst was characterized by various analyses such as FT‐IR, SEM/EDX, ICP‐AES, VSM, TEM, XRD, XPS and TGA. This nanocatalyst showed admirable catalytic activity for Suzuki‐Miyaura and Mizoroki‐Heck cross‐coupling reactions under mild conditions in water, and could be simply separated by an outer magnet and reused
