This study concerns the synthesis of β-sustituted β-nitrostyrenes by two procedures: addition of nitryl halogenides to double bonds, connected with the elimination of hydrogen halide, and condensation of aldehydes with substituted nitromethanes, and it compares the utilizability of the two procedures. Two of the substances prepared, methyl (Z)-nitro-3-phenylpropenoate and (Z)-4-phenyl-β-nitro-β-buten-2-one, were submitted to Z-E isomerization at various temperatures, and thermodynamic isomerization parameters were estimated from the dependence of the equilibrium constants on temperature.

By the action of H2S on boron halides (other than fluoride) one obtains the new substitution products BX2SH, BX(SH)2, and B(SH)3 along with the corresponding hydrogen halide. These halogenosulfhydroboranes are unstable and cyclize to cyclic boron sulfides, either (BSSH)3 or (BSX)3.In the case of boron bromide it is possible, by controlling the ratio of the reactants and the temperature of the reaction, to promote the formation of one of the three possible substitution products. Then by encouraging cyclization one may obtain, rapidly and selectively, either (BSSH)3 or (BSBr)3.Synthesis of (BSCl)3 was accomplished by dissolution of (BSSH)3 in liquid BCl3 and that of (BSI)3 by the action of H2S on solid BI3.

The rates of reaction of halide ions with ethylene oxide in neutral aqueous solution and the rate of hydrolysis of ethylene oxide in acid solution have been measured and the activation energies determined. From these data and from the ratio of glycol to chlorohydrin formed when ethylene oxide reacts with excess aqueous hydrogen halide, the rates of the acid-catalyzed addition of halide ions to ethylene oxide at 25 °C. have been estimated.
