Abstract

Combined UV/Vis and NMR spectroscopy gives access to complementary spectroscopic information on a single sample. When used in operando reaction monitoring, it is possible to precisely correlate this complementary information, providing deeper mechanistic insights. We showcase this approach on the condensation reaction of guaiazulene and 2,4-dinitrobenzaldehyde.
