Figure 2

LC-MS spectra depicting the reaction of an unprotected peptide with an sSPhos-ligated palladium biotin complex (OA-21) and the control reaction mixture without addition of peptide. All palladium reagents allowed for rapid transformation of biomolecules exhibiting similar reaction profiles and near-quantitative conversion. a Yield determined by LC-MS analysis of the crude mixture; see SI for details.
