Weby \ \ + \ \ ^ \ £ {+ * WebThe role of the precatalyst-associated labile halide (or pseudohalide) in the formation and stability of the palladacycle has been examined. It was found that replacing the chloride in the previous version of the precatalyst with a mesylate leads to a new class of precatalysts with improved solution stability and that are readily prepared from a wider range of … st thome more gateway

The same trends in precatalyst performance were observed when the catalyst loading was reduced from 0.5 mol% to 0.1 mol% (see SI). To assess if our results were relevant to other NHC ligands, we explored the catalytic activity of st thomas\u0027s school
