According to N. A. E. Millon,2 when dry finely powdered iodine is treated with ten times its weight of the most cone, nitric acid, a voluminous yellow powder is obtained which can be dried on a porous plate it contains iodine, oxygen, and nitric acid, and was regarded as nitroso-iodic acid. If the iodine nitrate is treated with a current of dry carbon dioxide or air, or dried on a porous tile over lime so long as nitrogenous fumes are given off, it is decomposed into iodine dioxide and... 

As indicated in connection with iodine tetroxide, N. A. E. Millon observed the formation of what he considered to be nitroso-iodic acid, and H. Kammorer what he considered to be iodine dinitrosyl tetroxide, I204(N0)8, or maybe O I.O.NO, by treating iodine with nitric acid, or nitrosylsulphuric acid. The yellow powder was considered by H. Kappeler to be iodine nitrate, T.NOj, vide 2. 19, 9. E. Briner said that mixtures of nitric and hydriodie acids do not form a univariant system like stabilized aqua regia, for the iodine produced as a result of the primary reaction is oxidized to iodic acid, with the evolution of nitric oxide. 

The use of iodine-containing pseudohalogens has been demonstrated to cause a variety of side reactions. Treatment of methyl 5-0-benzoyl-2,3-dideoxy-3-D-g/ycero-pent-2-enofuranoside (83, Scheme 22) with nitryl iodide afforded none of the desired addition product, but gave a quantitative yield of furfuryl benzoate (86). The same result was obtained by treating 83 with iodine nitrate, or with iodine alone.125 The rationale for this undesired result lies in the ability of iodine to act as a Lewis acid, polarizing the glycosidic bond, generating an oxacarbenium cation, which then decomposes to the stable aromatic 86. 

The reverse of reaction (5) may be a nighttime source of lO. Iodine nitrate may be formed by the reaction... 

Iodine nitrate was analyzed via the congeneric exchange reaction... 

Hypoiodous acid and iodine nitrate have been investigated with coupled cluster theory and the results extrapolated to the complete basis set limit. Together with revised thermochemistry for several ancillary molecules, the enthalpy changes of working reactions yields new thermochemistry for HOI and IONO2. The latter data, employed in unimolecular rate theory, appear to be consistent with kinetic measurements on the lO -l- NO2 reaction to within the uncertainties of the kinetic analysis. 

The chlorine, bromine, and iodine nitrates (X = Cl, Br, I) can also be prepared by the reaction of silver nitrate with the halides. 

Chlorine nitrate and HCl are considered to be the most important chlorine reservoir species in the stratosphere. Iodine nitrate has also been considered as a reservoir species for iodine radicals that could destroy tropospheric ozone, but photodissociation of IONO2 to form iodine radicals is only effective at temperatures below 290 K, at higher temperatures thermal decomposition takes place which does not yield iodine radicals. ... 

Several iodine nitrates in the oxidation state +III are known I(0N02)3 and CF3l(0N02)2- The other halogens do not form binary nitrates in the oxidation state +III. Iodine (III) nitrates are available by substitution of iodine(III)compounds... 

Examples of the selective substitution of phenol units in partially O-alkylated (or 0-acylated) calixarenes (reaction c)) are the bromination , iodination, nitration , formylation , chloromethylation , alkylation and coupling with diazonium salts. ... 

Significant amounts of the bicyclo[3.3.1]nonane adduct and of the octahydropental-enes were isolated also from the reaction of 3 with preformed iodine acetate and iodine acetate thallium (equation VS) whereas only the monocyclic 1,2-adducts were obtained from treatment of 3 with iodine azide, iodine isocyanate or iodine nitrate . The different propensity to give transannular products with these latter reagents has been related to the different positive charge density on carbons in the corresponding iodonium ion intermediates.

Position 2 of the ergoline skeleton is highly suitable for synthetic modification of EA by both electrophilic and radical substitution. Many modifications have been reviewed by Rutschmann and Stadler (1978) chlorination, bromination and iodination, nitration and reduction of nitro derivatives to amino derivatives and reaction with 2-methoxy-l, 3-dithiolane affording an intermediate which can be desulfurised to a 2-methyl derivative. Troxler and Hofmann (1959) described the oxidation of lysergic acid diethylamide (LSD) to 2-oxo-3-hydroxy-2, 3-dihydrolysergic acid diethylamide.

Chlorine nitrate CIONO2 and bromine nitrate B1ONO2 are important reservoir molecules formed by the chain termination reactions, CIO + NO2 and BrO + NO2, in the CIO and BrOx cycles in the stratosphere, respectively. Iodine nitrate IONO2 plays a similar role in the in the iodine chemistry in the troposphere.
