Ground-state dioxygen undergoes metal-free [3 + 2]-annulations with allenes and nitrosoarenes under ambient conditions
The cycloadditions of molecular dioxygen with neutral π-bond motifs rely heavily on singlet-state (1)O(2), whereas ground state (3)O(2) is chemically inactive. Here we report novel [3 + 2]-annulations among ground-state (3)O(2) (1 bar), allenes, and nitrosoarenes at low temperatures, efficiently yie...
