Unveiling leaching-oxidizing-landing paths of Pd single-atom catalyzed Suzuki-Miyaura reaction by ambient mass spectrometry.

ABSTRACT: The palladium-catalyzed Suzuki-Miyaura cross-coupling (SMCC) reaction is an essential technique for C-C bond formation. It is considered to occur through two distinct pathways involving homogeneous and heterogeneous mechanisms. However, there is still debate about these mechanisms due to the lack of direct structural evidence in both spatial and temporal terms, especially regarding the conversion of active Pd species. In this study, the Pd single-atom catalyst (Pd SAC) SMCC reaction was monitored in real-time using ambient mass spectrometry (AMS) to study the conversions of Pd species both on the catalyst surface and in the liquid phase. This revealed a leaching-oxidizing-landing path as a contributors to the heterogeneous process which involves heterogeneous oxidative addition, Pd leachin
