N2 - Radical formation in ball-milled mono- and di-saccharides was found to be especially effective for a-lactose monohydrate and α-d-glucose monohydrate. For these two sugars, spin-trapping experiments were performed by using pentamethyl nitrosobenzene (PMNB) and tri-tert-butylnitrosobenzene (BNB). The sugar radicals could not be trapped directly, but they transferred a hydrogen atom to BNB and an electron to PMNB. Based on the e.s.r. spectra in the solid state and the results of the spin-trapping experiments, a mechanism for radical formation is proposed.
