The C−F bond activation of pentafluoropyridine and 2,3,5,6-tetrafluoropyridine at [Ni(cod)2] (cod=1,5-cyclooctadiene) in the presence phosphine PPh2(Ind) (Ind=3-methyl-2-indolyl) led to formation nickel(II) fluorido bis(phosphine) complexes trans-[Ni(F)(2-C5NF4){PPh2(Ind)}2] trans-[Ni(F)(2-C5HNF3){PPh2(Ind)}2]. are characterized by intramolecular hydrogen bonds between NH group ligands ligand. ...

Abstract Mirfentanil, a fentanyl derivative that is μ ‐opioid partial agonist, hyperpolarised via Signal Amplification By Reversible Exchange (SABRE), para ‐hydrogen‐based technique. [Ir(IMes)(COD)Cl] (IMes=1,3‐ bis (2,4,6‐trimethylphenyl)imidazole‐2‐ylidene, COD=cyclooctadiene) was employed as the polarisation transfer catalyst. Following at 6.5 mT, pyrazine‐protons were enhanced by 78‐fold (p...

The title compound, C(13)H(16)N(2)O(3)S, is a thio-urea derivative with benzoyl and propoxycarbonyl-methyl groups attached to the two terminal N atoms. These groups adopt trans and cis configurations, respectively, with respect to the S atom across the thio-urea C-N bonds. The compound crystallizes in the P2(1)/c space group with Z = 8, resulting in two unique molecules in the asymmetric unit l...

In this work, we report the transfer of alkyl bis- and tris(pyrazolyl)aluminates metalloligands to an electron-rich organotransition metal center. The 16-electron heterobimetallic complexes rhodium [Rh(COD){Al(Ph2pz)2Me2}] (3) [Rh(COD){Al(Ph2pz)3Me}] (4) were obtained by metathesis reaction sodium (1) tris(pyrazolyl)aluminate (2) with [RhCl(COD)]2. For 3, 1H 13C NMR in solution along DFT calcul...
