Although diazoalkanes are important carbene precursors in organic synthesis, a comprehensive mechanism of photochemical for-mation of carbenes from diazoalkanes has not been proposed. Synergy of experiments and computations demonstrates the in-volvement of higher excited singlet states in the photochemistry of diazoalkanes. In all investigated diazoalkanes, excitation to S1 results in nonreactive internal conversion to S0. On the contrary, excitation to higher-lying singlet states (Sn, n > 1), drives the reaction toward a different segment of the S1/S0 conical intersection seam and results in nitrogen elimination and formation of carbenes.
