The reactions of 1-aryl-2-bromodiazene 1-oxides with HCl in nonaqueous media give aryldiazonium chlorides, while 1,3,3-substituted triazenes-1 are formed in the reactions with secondary amines. Using 2-{15N} label, it was shown that the aryl group does not migrate in these reactions....

Record the volume of acid and base used. Use precision instrument gives us… therefore have to measure to the hundredth (as far as know and then estimate one) Refill burets and complete lab again from step 1, but this time run 15 mL into flask...
Acid—base and redox reactions in binary systems of sodium nitrite and several oxides with different acidity and oxidizing ability have been investigated. Kinetic parameters have been obtained by analyzing thermogravimetric data under a constant heating rate. Sodium peroxide is the main basic species in...
A study was made of the reactions of dialkylisothiocyanatoarsines with 伪 -oxides and thiiranes. A mechanism was proposed for the formation of the 2-thiocyanatoalkyl esters of arsinous (thioarsinous) acids. Some characteristics of the exchange reactions of the 2-thiocyanatoalkyl esters of ...
Reaction of cyclohexene oxides with phosphodiesters - towards understanding the reaction of benzo[a]pyrene diol epoxide with DNA Phosphodiesters react with cyclohexene oxides to give phosphotriesters with high stereo- and regiospecificity.
