Transformations of myo-inositol hexa-0-nitrate under the action of amines

Reactions of myo-inositiol hexa-0-nitrate with ammonia and primary amines yield tetrahydroxy-1,4-benzoquinone derivatives, viz., its tetraammonium salt and its diimines, respectively. Reactions with secondary and tertiary amines give salts of rhodizonic acid, which are converted into salts of croconic acid under certain conditions. The reactions with secondary amines involve intermediate formation of radical species, which were dectected by ESR spectroscopy. A scheme for the chemical transformations of myo-inositol hexa-0-nitrate under the action of amines was proposed.
The photochemistry of the rhodizonate dianion in aqueous solution
Iraci, G.,Back, M. H.
, p. 1293 - 1294 (2007/10/02)
The photochemistry of the rhodizonate dianion at 483 nm has been studied in aqueous solution at pH 8.3.In the absence of oxygen no reaction was observed.In the presence of oxygen, 6.2 x 10-5 M, the dianion was consumed with a quantum yield of 0.044.The oxidation apparently did not involve the formation of O2(1Δg).Electron transfer from the excited dianion was observed with methyl viologen.
