Platinum Complexes from C–H Activation of Sterically Hindered [C^N] Donor Benzothiophene Imine Ligands: Synthesis and Photophysical Properties

et al. 2020

Primary amines and benzothiophene-3-carboxaldehyde were reacted to give four large, bulky imine ligands. These imine ligands were reacted with a tetramethyl platinum dimer and by heteroatom-assisted C–H activation, both monometalated compounds and bismetalated compounds were synthesized. In all cases, five-membered platinacycles were formed. The compounds were characterized by NMR spectroscopy, and one bismetalated compound was characterized by single-crystal X-ray diffraction. The UV–vis absorption and emission spectra and the excited-state lifetimes were recorded for these complexes. Density functional theory (DFT) and time-dependent-DFT calculations were performed to aid in the assignment of the absorption and emission spectra of the newly synthesized complexes.

“…There are two monoclinic, cis-[Pt{η 2 -Ph 2 P(η 2 -C 4 H 8 )PPh 2 }{C 6 F 5 }(Cl)]Me 2 CO complexes [29] which exist in two isomeric forms. These isomers differ mostly by degree of distortion and are classical examples of distortion isomerism [56][57][58].…”

This manuscript summarizes and analyzes X-ray data of monomeric cis-PtP 2 CCl derivatives. These complexes crystallize in the following crystal systems: tetragonal, P4 2 /n (3), triclinic, Pī (10), orthorhombic, P2 1 2 1 2 1 (prevails)(16), and monoclinic, P2 1 /c (prevails) (36) examples. There are three subgroups of the respective complexes: Pt(η 1-PL) 2 (η 1-CL)(η 1-Cl); Pt(η 2-P 2 L)(η 1-CL)(η 1-Cl) and Pt(η 1-PL)(η 2-P,CL)(η 1-Cl). The chelating P,P-donor ligands form: four-(POP, PCP), five-(PC 2 P), six-(PC 3 P, PCNCP), seven-(PC 4 P) and even ten-(PCNCNCNCP) membered rings. The chelating P.C-donor ligands create three-(PC), four-(PCC) and five-(PC 2 C) membered rings. The mean Pt-L bond distance elongates in the sequence: 2.10 Å (C, trans to P) < 2.222 Å (P, trans to Cl) < 2.312 Å (P, trans to C) < 2.360 Å (Cl, trans to P). There are examples which exist in two isomeric forms, of the distortion isomer type.
