An efficient synthesis of thiazolidine-2,4,5-triimine derivatives was developed via Ni-catalyzed oxidative double isocyanide insertion to thioureas under air conditions, in which thioureas play three roles as a substrate, a ligand, and overcoming isocyanide polymerization. The reaction is featured by employing a low-cost and low loading Ni(acac)2 catalyst, without any additives, and high atom economy. This is the first example to directly apply a Ni(II) catalyst in oxidative double isocyanide insertion reactions.

A novel and expeditious approach for the synthesis of N-fused and 3,4-disubstituted 5-imino-1,2,4-thiadiazole derivatives has been achieved through the molecular iodine-catalyzed oxidative cyclization of 2-aminopyridine/amidine and isothiocyanate via N-S

Inhibiting effect of 1-phenacylmethylpyridinium bromides containing urea or thiourea substituents in the pyridinium ring on steel and zinc corrosion in sulfuric acid solutions was studied.

The following molecules were found to have intramolecular hydrogen bonding between the N′H and the pyridine nitrogen and intermolecular hydrogen bonding between the NH and a thione sulfur of a second molecule to form dimers: N-(2-pyridyl)-N′-(4-methoxyphe
Synthesis and antibacterial activity of pyridyl thioureas and arylthiosemicarbazones
Kumar,Singh,Pandeya
, p. 238 - 242 (2007/10/03)
[N-(2-pyridyl)-N'-(4-(un) substituted] thioureas and (substitutedaryl)thiosemicarbazones were synthesised and evaluated for their antibacterial activity. All aryl thiosemicarbazones showed good activity against Aeromonas hydrophilia and Salmonella typhimuriurn. But none of the pyridyl thioureas showed any prominent activity against tested bacteria.
Interactions between substituted thioureas and π-acceptors
Mohamed,Hassan,Ibrahim,Semida,Mourad
, p. 592 - 595 (2007/10/02)
Charge-transfer (CT) interactions between some N-aryl-N'-heterocyclic thioureas and both tetracyanoethylene (TCNE) and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) were investigated spectroscopically. The formed CT complexes and the solvent effect on CT complexation are discussed. N-Aryl-N'-(2-pyridyl)-thioureas 1 a-d reacted with TCNE to give cyanothiourea derivatives 6, however in case of DDQ, the adducts 7 were obtained.
Anticonvulsant activity and succinate dehydrogenase inhibitory property of new substituted thiobarbiturates
Dhasmana,Barthwal,Pandey,et al.
, p. 635 - 637 (2007/10/02)
Eight 1-aryl-3-(2-pyridyl)thiobarbiturates were synthesized and evaluated for their anticonvulsant property and their ability to inhibit succinate dehydrogenase activity of rat brain homogenates. These substituted thiobarbiturates (100 mg./kg., i.p.) provided 20-60% protection against pentylenetetrazol-induced convulsions in albino mice. Low toxicity of these compounds was reflected by their high approximate LD50 values which were found to range from 500-1000 mg/kg. All substituted thiobarbiturates (1mM) inhibited in vitro succinate dehydrogenase activity and the degree of inhibition ranged from 10-72%.
