摘要：

A study was conducted to demonstrate the behavior of a Pd 0-N-heterocyclic carbene (NHC) complex under hydrogen (H2) and its catalytic performance in hydrogenation of C-C multiple bonds. It was also demonstrated that [Pd(SIPr)(PCy3) solution was a highly active catalyst for the hydrogenation of a wide range of alkenes and alkynes using H2. It was observed that [Pd(SIPr)(PCy 3) underwent an oxidative addition, leading to the trans-dihydride species [Pd(H2)(SIPr))(PCy3). The presence of the species was also supported by1H NMR spectroscopy investigations. It was also demonstrated that the catalytic system was efficient for functionalized and non-functionalized terminal and internal alkenes.
