Electronic Properties of N-Heterocyclic Carbene (NHC) Ligands: Synthetic, Structural, and Spectroscopic Studies of (NHC)Platinum(II) Complexes
Abstract
N-Heterocyclic carbene complexes of platinum(II) have been synthesized, notably monocarbene complexes cis -[(IPr)Pt(dmso)(Cl) 2 ], 6, cis -[(IMes)Pt(dmso)(Cl) 2 ], 7, cis -[(SIPr)Pt(dmso)(Cl) 2 ], 8, cis -[(SIMes)Pt(dmso)(Cl) 2 ], 9, and cis -[(TTP)Pt(dmso)(Cl) 2 ], 10 . All complexes have been fully characterized by multinuclear NMR spectroscopy. Complex 7, 9, and 10 have been characterized by X-ray crystallography. The data obtained have allowed for the differentiation between electronic contributions (σ and π) present in the Pt−NHC bond. Supported by computational analyses, the percentage of π back-donation from the metal to the NHC is found to be on the order of 10%. More interestingly, we find that saturated NHC (SIPr and SIMes) are more efficient π back-acceptors than their unsaturated NHC congeners (IPr and IMes). The synergistic effect between π back-donation and σ donation present in the saturated NHC systems results in increased electron density at the platinum center compared to the bonding situation in the unsaturated NHC examples.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
