Binuclear silver(I) and copper(I) complexes, and , with bridging diphenylphosphine ligands were prepared. In , the silver(I) center is located inside a trigonal plane composed of three phosphorus donors from three separate and bridging dppm ligands. The fourth coordination site is filled with neighboring silver(I) ions.

The synthesis utilized phosphine and sulfur donors from the dialkyldithiophosphate and borate families, specifically Na[SH2B(mt)]. These complexes are designated as [(dppf)AgSP(S)(OPr)] (1), [SHB(mt)Ag(μ-dppf)AgSHB(mt)] (2), [(dppf)Ag(μ-dppf)Ag(dppf)] (3), and [(dppe)AgSHB(mt)] (5).

Among the important aspects of CPR is ensuring the correct airway position of the patient, which is typically monitored by human tutors or supervisors. This study aims to utilize deep transfer learning for the detection of the patient's correct and incorrect airway position during cardiopulmonary resuscitation.

A simple and efficient procedure for synthesizing novel pincer-type tridentate N-heterocyclic carbene bisphenolate ligands is reported. The synthesis of pincer proligands with ,'-disubstituted imidazoline core, and , was carried out via triethylorthoformate-promoted cyclization of either ,'-bis(2-hydroxy-3,5-di--butylphenyl)cyclohexanediamine, , or ,'-bis(2-hydroxyphenyl)cyclohexanediamine, , in the presence of concentrated hydrochloric acid. Cyclic voltammograms of the ligands revealed ligand-centered redox activity, indicating the noninnocent nature of the ligands.
