1.1- dinitroethane potassium salt

Phenyltrinitromethanes are similarly obtained from the nitration of gem-nitronitronate salts with a solution of dinitrogen tetroxide in ether. 1,1,1-Trinitroethane (73) can be formed in this way from the potassium salt of 1,1-dinitroethane (24). Nitrolic acids, the products formed... 

Other early observations of photochromic systems include ter Meer s potassium salt of dinitroethane (9) and Phipson s gate post painted with photochromic lithopone pigment (10). 

Among the substrates were 1-nitropropane, 2-nitrobutane and nitrocyclohexane the less reactive ethyl a-nitrocaproate was also phenylated, at 55°C. 1,1-Dinitroethane and 1,1-dinitropropane in the form of their potassium salts were phenylated in boiling t-butanol (67%) [43],... 

The potassium salts of 1,1-dinitroethane and 1,1-dinitropropane are also phenylated by diphenyliodonium tosylate (25) in rert-butanol under reflux (yields 67-68%). Poor yields were obtained when the reaction was performed in DMF (5%). 4... 

Potassium salts of phenyldinitromethane, 1,1-dinitroethane, and 1,1-dinitropro-pane decompose at 80 °C in DMF and other polar solvents to give nitrile oxides...
