Platinum(II) and Platinum(IV) Porphyrin Pincer Complexes: Synthesis, Structures, and Reactivity

Pt(II) and Pt(IV) porphyrin pincer complexes were synthesized and characterized. Their structures and electronic properties were influenced by the valence state of platinum at the outer coordination site. The considerable distortion in the porphyrin core of the Pt(II) complex was relieved in the Pt(...

description Pt(II) and Pt(IV) porphyrin pincer complexes were synthesized and characterized. Their structures and electronic properties were influenced by the valence state of platinum at the outer coordination site. The considerable distortion in the porphyrin core of the Pt(II) complex was relieved in the Pt(IV) complex, due to the change of the coordination geometry of platinum. Oxidation of the phenylplatinum(II) pincer complex with iodine induced a facile carbon−carbon bond formation reaction at the meso position via reductive elimination.
