General Description

Benzenethiol, 3,4-diamino- (9CI) is an organic compound with the chemical formula C6H8N2S. It is a derivative of benzenethiol, which is a compound with a sulfur atom bonded to a benzene ring. The addition of two amino groups in the 3 and 4 positions of the benzene ring gives this compound its unique chemical properties. It is used in various industrial applications, including as a reagent in organic synthesis and as a precursor to other organic compounds. Additionally, it has potential applications in the pharmaceutical and agrochemical industries. Benzenethiol, 3,4-diamino- (9CI) should be handled with care, as it can be toxic if ingested or inhaled and can cause skin and eye irritation.

Ratiometric SERS imaging and selective biosensing of nitric oxide in live cells based on trisoctahedral gold nanostructures

Herein, a ratiometric SERS probe was created for monitoring nitric oxide (NO) by designing a novel molecule, 3,4-diaminobenzene-thiol, and immobilizing this molecule onto trisoctahedral gold nanostructures with superior SERS capability. The established probe possessed good selectivity and biocompatibility, high sensitivity and accuracy, thus enabling imaging and biosensing of NO in live cells.

On benzo[b][1,4]diazepinium-olates, -thiolates and -carboxylates as anti-Hueckel mesomeric betaines

2,3-Diaminophenol 4, 3,4-diaminophenol 5, 4-methoxy-1,2-diaminobenzene 6, 3,4-diaminobenzenthiol 7, 2,3-diaminobenzoic acid 8, and 3,4-diaminobenzoic acid 9 were reacted with 2,4-pentanedione to yield the corresponding benzo[b][1,4]diazepinium salts, respectively. The hydroxy-benzo[b][1,4]diazepinium salts 17 and 18 do not form mesomeric betaines (MB) on deprotonation. Instead, they are converted into the diimines 24 and 25. By contrast, the 7-mercaptobenzo[b][1,4]diazepinium salt 20 yields the corresponding thiolate on increasing the pH of the solution. This MB, which possesses 4n π-electrons, does not fit into the classification system of heterocyclic mesomeric betaines accepted today. Deprotonation of the betaine results in the formation of an instable anionic thiolate 31 which oxidizes immediately to the disulfide 32. The carboxy derivatives 21 and 22 readily form cross-conjugated mesomeric betaines. Whereas the diimine 34 proved to be instable, the sodium salt of the diimine 36 was unambiguously characterized. An X-ray single crystal analysis of 22 as its picrate is presented in order to gain additional insights into these 4n π-electron systems.
