“…Our initial synthetic methods were established by 2006. 4,12,13 Since then, our research has focused on the investigation of the external stimuliresponsive behavior of secondary thioamide (sec-TA)-based S^X^S (X = C or N) pincer complexes. Figure 1 shows the basic physical properties of simple sec-TA and secondary amide (sec-A); among these, the most relevant are: a) suitable hydrogen-bond donor properties, 14 b) high acidity, 15,16 and c) deprotonation-driven structural-changeability.…”

This highlight review describes recent progress in thioamidebased transition-metal complexes, including their preparation methods and functionalities. In particular, pincer organometallics with secondary thioamide ligands are unique tools that can be used for applications in various areas such as chemical-sensor materials, tunable redox-potential complexes, polymer hybridluminescence materials, building blocks for multinuclear complexes, and catalysts for cross-coupling reactions.

“…e selectivity of 1 and 2 toward Pd, Au, and Ag is higher than conventional adsorbents having thiocarbonyl groups such as thioamide [26][27][28][29][30][46][47][48][49][50][51][52], thiourethane [32,34,36], and thiourea [11,25,[53][54][55][56][57][58][59] structure [61]. e lower selectivity of these thiocarbonyl structures can be ascribed to the tautomerism between thiocarbonyl and thiol.…”

“…However, thiol groups are susceptible to oxygen-converting thiols into disulfides via oxidative coupling [44]. iocarbonyl moieties such as thioamide [26][27][28][29][30][47][48][49][50][51][52][53], thiourethane [31,33,35,37], and thiourea [11,25,[54][55][56][57][58][59][60] have also been examined as stable adsorbents. We also have found that a polymer bearing N,N-dialkylthiourethane moieties has high adsorption ability to Pd and Au, but the adsorption from aqueous solutions only proceeded in the presence of organic solvents such as chloroform due to the hydrophobic nature of the backbone [35].…”

Novel hydrophilic sulfur-containing adsorbents for noble metals were prepared by the radical terpolymerization of a methacrylate bearing dithiocarbonate moieties (DTCMMA), hydrophilic monomers, and a cross-linker. e resulting adsorbents efficiently and selectively adsorbed noble metals (Au, Ag, and Pd) from various multielement aqueous solutions at room temperature owing to the thiocarbonyl group having high affinity toward noble metals. e metal adsorption by the adsorbents was proceeded by simple mixing followed by filtration.e noble metal selectivity of the adsorbent obtained from DTCMMA and N-isopropylacrylamide was higher than that of the adsorbent obtained from DTCMMA and N,N-dimethylacrylamide due to the lower nonspecific adsorption.

“…Direct cyclopalladation of thioamide-based pincer ligands proceeded smoothly also in the case of ligands 8a-c bearing sterically hindered pyrrolidine, piperidine, and morpholine units, leading to complexes 9a-c in high yields (Scheme 3) [33,34]. Besides the fundamental aspects of formation, S,C,S-pincer complexes based on bis(thioamide) derivatives provoked considerable interest owing to their remarkable photophysical properties [35,36].…”

Rapid development of pincer chemistry over the last several decades made a substantial contribution in extension of theoretical and practical organometallic chemistry as well as organic synthesis, catalysis, and materials science. This review is devoted to relatively new types of nonclassical pincer compounds bearing thione sulfur donors incorporated into thiophosphoryl and/or thioamide groups. The discussion is focused on synthetic aspects and structural features of symmetrical and hybrid S,C,S-pincer ligands and complexes with particular attention to the practically valuable properties.
