我们报告了七个新型骨架功能化的N-苯基-1,3-噻唑-2-亚基铂(II)配合物的合成及其光物理性质。通过苯胺与二硫化碳和不同的α-卤代酮化合物的反应制备电子上多样化的N-苯基-1,3-噻唑-2-硫酮。氧化脱硫和盐复分解反应可生成具有六氟磷酸抗衡离子的所需NHC前体。另外,提出了使用高价碘通过N-芳基化合成N-苯基-1,3-苯并[ d ]噻唑四氟硼酸酯的新途径。所有配合物均由相应的NHC前体通过一锅法使用银(I)氧化,重金属化成铂,并在碱性条件下与β-二酮乙酰丙酮反应。这些复合物在2 wt%的PMMA膜中表现出强烈的磷光,量子产率高达72%,衰减寿命为8.8-12.3μs。1,3-噻唑部分的4-和/或5-位以及N-苯基-1,3-苯并[ d ]的甲基和苯基以及酯取代基的影响噻唑衍生的主题进行了讨论。4,5-未取代的-N-苯基-1,3-噻唑-2-亚烷基铂(II)乙酰丙酮基络合物作为本研究的参考文

A series of 2(3H)‐thiazole thiones 3–5 was synthesized and evaluated for tyrosinase inhibition and DPPH radical scavenging activities. Among them, 3‐methyl‐4‐phenyl‐2(3H)‐thiazole thione (4a) showed good tyrosinase inhibitory activity, even better than that of the well‐known tyrosinaseinhibitor, namely, kojic acid. From the structure–activity point of view, although it was found that the phenolic

Abstract A one‐pot facile synthesis of thiazole‐2(3H)‐thiones (4) has been achieved by hypervalent iodine oxidation of ketones (1) using [hydroxy(tosyloxy)iodo]benzene, followed by the treatment of the reaction mixture with dithiocarbamate salts (3). The intermediate α‐tosyloxyketones (2) have also been isolated and converted to the target compounds.
