A very brief description of using TR spectroscopy to study the photodeprotection and photosolvolytic rearrangement reactions of the p-hydroxyphenacyl diethy-Iphosphate (HPDP) compound will be given here as an example. ... [Pg.162]

Photoinduced electron transfer from donors such as prenyl acetate, geranyl acetate, all-/ra/w-famesyl acetate, and all-/ra j-geranylgeranyl acetate to 1,4-dicyano-2,3,5,6-tetramethylbenzene, 1,4-dicyanonaphthalene, and 9,10-dicya-noanthracene in the presence of l,r-biphenyl as co-donor in acetonitrile produces the radical cation of biphenyl and the radical anion of the electron acceptors. Geranyl acetate is observed to photocyclise, and the mechanism of this process which involves reaction of its radical cation with water is discussed. Allyl glycosides (76) can be photodeprotected to give (77) via (78) by irradiating with di-t-butyl peroxide in the presence of bromotrichloro-methane. ... [Pg.216]

Ultrafast time-resolved transient absorption and resonance Raman spectroscopy of the photodeprotection and rearrangement reactions of p-hydroxyphenacyl phosphates (72), via intermediate M, have been described (Scheme 13). ... [Pg.131]
