Photochemical decarbonylation of cyclobutanedione 1 leads to the blue oxyallyl, which could be trapped in the solid with a lifetime of 42 minutes
Photochemical decarbonylation of cyclobutanedione 1 in the crystalline state leads to the blue oxyallyl, which could be trapped in the solid at ambient temperature with a lifetime of 42 minutes. The same spectrum in solution has a lifetime that is more than a trillion times shorter! (i.e., 3.3 ps in dichloroethane).
