Diarylplatinum(II) Compounds as Versatile Metallating Agents in the Synthesis of Cyclometallated Platinum Compounds with N-Donor Ligands

“…Evidence from the fact that cis configuration of the platinum precursor is not required comes from the fact that double cyclometallation of 3,6-bis(2-thienyl)-1,2,4,5-tetrazine has been achieved from the precursor trans-[Pt (2,4,6-Me 3 C 6 H 2 ) 2 (dmso) 2 ] in a reaction leading to a dinuclear platinum(II) compound [55]. [60] in order to compare the results with those obtained when [Pt 2 Me 4 (μ-SMe 2 ) 2 ] was used as precursor.…”

“…Taking into account the results described above for ligands containing two nitrogen atoms, isomerization to the adequate isomer should be more facile for ligands containing one single nitrogen, thus allowing formation of seven-membered platinacycles even for the less prone bromo derivatives. 2 . This result can be related with the strength of the C-F bond and the lower reactivity of the later substrates toward intramolecular activation of σ bonds.…”

“…Cyclometallated platinum compounds containing N-donor ligands have attracted a great deal of attention because of their potential interest in both areas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. For this reason, the development of new methods for the preparation of cycloplatinated compounds containing N-donor ligands is a pursued goal.…”

“…In contrast to cyclopalladation reactions for which Pd(OAc) 2 is a very useful precursor leading to formation of a wide variety of palladacycles [18,19], an analogous "universal" starting material is unknown for cycloplatination reactions. Recent reports on cycloplatination reactions proved that cis-[PtCl 2 (dmso) 2 ] is a reasonable metallating agent leading to higher yields and cleaner reactions than the more classical OPEN ACCESS K 2 [PtCl 4 ] starting material [20][21][22][23][24][25][26][27][28][29][30]. In these systems, the labile sulfoxide ligands are easily replaced for nitrogen atoms, thus affording the required initial coordination of the nitrogen-donor ligand, which is followed by ortho-metallation.…”

Light-induced catalytic and cytotoxic properties of phosphorescent transition metal compounds with a d 8 electronic configuration

“…Metal compounds have long been demonstrated to have diverse applications in catalysis [1,2], therapeutics usages [3,4] and also as light-emitting materials [5,6]. In the face of the ever-growing demand for energy 2013 The Author(s) Published by the Royal Society.…”
