Novel Dependence of the Bond Cleavage Pattern of Bis(2-phenylbenzoyl) Peroxide on the Irradiation Wavelength

Novel Dependence of the Bond Cleavage Pattern of Bis(2-phenylbenzoyl) Peroxide on the Irradiation Wavelength

Bis(2-phenylbenzoyl) peroxide (2-PhBPO) photodecomposed by 100% O–O bond cleavage to give mainly biphenyl-2,2′-carbolactone on 313 nm irradiation, however, on 254 nm, the photodecomposition proceeded through 60% two bonds cleavage (simultaneous C–C and O–O bonds cleavage).
