Generation and Characterization of the First Persistent Platinum(I)‐Centered Radical

Abstract: The first persistent platinum(I)-centered radical was generated by homolytic cleavage of aP t À HgSiR 3 bond of am ercury-substituted platinum(II) complex. The Pt I radical was characterized by EPR spectroscopy, chemical trapping experiments,and density functional theory (DFT) calculations. Scheme 1. Synthesis and photolysiso fplatinum complexes 3.

“…Platinum(0) complexes can act as one‐electron reductants and react with various alkyl halides by a free radical mechanism . Even though it is possible to isolate and characterize persistent platinum(I) complexes, their application to trap alkyl radicals has not been well investigated to date . Along with their use as catalysts in Kharasch additions, Pt complexes also catalyze the radical transformation of alkyl iodides into the corresponding esters under CO atmosphere in the presence of alcohols…”

“…Platin(0)‐Komplexe können als Ein‐Elektronen‐Reduktionsmittel agieren und reagieren mit verschiedenen Alkylhalogeniden über einen radikalischen Mechanismus . Obwohl es möglich ist, persistente Platin(I)‐Komplexe zu isolieren und zu charakterisieren, ist die Anwendung als Radikalfänger bisher nicht gut untersucht . Neben ihrer Verwendung als Katalysator in Kharasch‐Additionen katalysieren Pt‐Komplexe radikalische Umsetzungen von Alkyliodiden zu den entsprechenden Estern unter CO‐Atmosphäre in Anwesenheit von Alkoholen…”
