Semi-flexible bipyridine derivatives incorporating alkyl spacer groups between the pyridyl rings have been demonstrated to yield dinuclear palladium(II) species related to those discussed in Section 7.2 of this chapter.Thus, insertion of -CHjCHj- or -CH2(CgF4)CH2- groups between the 4- and 4 -positions in the parent bipyridine ligand leads to the formation of 2 2 (metal ligand) complexes of type 32 on reaction of these extended bipyridine derivatives with dinitro(ethane-... 

These compounds all have lachrymatory power, especially tetrachloro dinitro ethane, which is much more powerful in this respect than chloropicrin.

The structure, synthesis, and properties of some persubstituted 1,2-dinitro-ethanes have been reported,and the use of KMn04 provides a simple and effective means for the conversion of nitroparaffin salts into pure aldehydes and ketones (Nef reaction) in high yield. In addition, the nitrolysis of N-t-butylamines provides disubstituted iV-nitramines in high yield. ... 

Dinitro-2-butene may be prepared from 1-chloro-l-nitro-ethane by the same procedure, in 30% yield. The compound melts at 28-28.5° and has a boiling point of 135°/11 mm. Commercially available 1-chloro-l-nitroethane contains about 10% 1,1-dichloro-l-nitro-ethane and 2-chloro-2-nitropropane which cannot be separated by distillation, but these impurities do not interfere with the preparation. Distillation of 2,3-dinitro-2-butene behind safety glass in a nitrogen atmosphere is advisable. The submitters, in preparing this compound, have had one explosion over a period of ten years. 

Several of this group are explosives of moderate to considerable sensitivity to impact or friction and need careful handling. Fluorodinitromethane and fluorodini-troethanol are also vesicant [ 1 ]—[4]. l-Fluoro-l,l-dinitro derivatives of ethane, butane, 2-butene and 2-phenylethane are explosive [5], Among the preparations of a series of energetic and explosive compounds, that of N, N, N, A /-tctrakis(2-fluoro-2,2-dinitroethyl)oxamide is especially hazardous, as it involves heating an undiluted explosive to a high temperature [6],... 

Titanium dioxide suspended in an aqueous solution and irradiated with UV light X = 365 nm) converted benzene to carbon dioxide at a significant rate (Matthews, 1986). Irradiation of benzene in an aqueous solution yields mucondialdehyde. Photolysis of benzene vapor at 1849-2000 A yields ethylene, hydrogen, methane, ethane, toluene, and a polymer resembling cuprene. Other photolysis products reported under different conditions include fulvene, acetylene, substituted trienes (Howard, 1990), phenol, 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 2,6-dinitro-phenol, nitrobenzene, formic acid, and peroxyacetyl nitrate (Calvert and Pitts, 1966). Under atmospheric conditions, the gas-phase reaction with OH radicals and nitrogen oxides resulted in the formation of phenol and nitrobenzene (Atkinson, 1990). Schwarz and Wasik (1976) reported a fluorescence quantum yield of 5.3 x 10" for benzene in water.

Tetranuclear aromatic diamines were prepared on the basis of bis-phenols derived from 1,1,1-trichloro-2,2-di-(p-methoxyphenyl)-ethane under the action of pyridine hydrochloride [26, 27]. Interaction of the bis-phenols with two-fold molar amounts of p-nitrochlorobenzene led to the formation of 4,4 -bis(/ -nitrophenoxy [-arylenes, which were reduced to the corresponding 4,4 -bis(/ -aminophenoxy[-arylenes [28] (Scheme 2.11). Similar compounds containing two additional amino groups were prepared by the interaction of 3,3 -dinitro-4,4 -dichlorobenzophenone with two-fold molar amounts of potassium p-nitrophenolate [29] followed by reduction of the tetranitro compounds thus formed [29] (Scheme 2.12).
