Photobinding of Flutamide to Phospholipid Vesicles: Additional Evidence for Photoprocesses Unexpectedly Triggered by Conformational Changes in the Bilayer

“…Planarization of the NO 2 group with consequent loss of the twisted conformation would lead in fact to a less extended overlap of the p-atomic-orbital of the O-atom with the adjacent orbital of the aromatic ring. As well-documented in the literature [28] [29], the twisted conformation is an essential prerequisite for the NO 2 to nitrite photorearrangement responsible for the formation of 1. The consequence of the planarization is, in turn, reflected in the logical increase of biradical character of the n,p* triplet and in the consequent high ability of this latter to abstract H-atoms in the presence of a suitable H-donor.…”

Comparison of photoreactions of flutamide in acetonitrile and 2-propanol solvents in the absence of cage-forming compounds

“…Aromatic nitro compounds are known to undergo various photoreactions, such as photosubstitution, photoredox reactions, photodissociation and photo-induced nitro-nitrite rearrangement [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Photosubstitution and photoredox reactions have been well investigated [1][2][3][4][5][6][7][8][9][10][11], but photodissociation and nitro-nitrite rearrangement have not yet been fully elucidated [10][11][12][13][14][15][16][17].…”

“…Photosubstitution and photoredox reactions have been well investigated [1][2][3][4][5][6][7][8][9][10][11], but photodissociation and nitro-nitrite rearrangement have not yet been fully elucidated [10][11][12][13][14][15][16][17]. Nitro-nitrite rearrangement and photodissociation have low reaction efficiencies, and the short-lived intermediates of these reactions are difficult to observe.…”

Investigation of photoreaction for 2-nitrobenzofuran and its 3-methyl derivative

“…While photosubstitution and photoredox reactions were well investigated [1][2][3][4][5][6][7][8][9][10][11][12], photodissociation and nitro-nitrite rearrangement reactions have not been completely elucidated [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. This is due to the fact that nitronitrite rearrangements and photodissociation reactions have low reaction efficiencies, which makes it difficult to observe any of the short-lived reaction intermediates.…”

“…The photoreactions of nitro-substituted aromatic hydrocarbons have also been thoroughly examined [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][26][27][28]. In the photoreactions of nitro-substituted aromatic heterocycles, R. Hunt and S. T. Reid specifically investigated the photorearrangements of fivemembered nitroheteroaromatic systems such as 2-nitrofuran and 2-nitropyrrole.…”
