Abstract The electric dipole moments of acetyldiazomethane (MeCOCHN2) and 1-acetyl-1-diazo-ethane (MeCOMeN2) between 10 and 70 °C have been measured. Using appropriate group and bond moments, the concentrations of the two rotamers present in each have been calculated and, hence, the equilibrium constant for the cis ⇆ trans equilibrium at the various temperatures.The change in standard enthalpy (⊿H°), standard free energy (⊿G°) and standard entropy (⊿S°) are reported for the conversion of one mole of cis isomer to trans isomer.

Styrene Derivatives

The electric dipole moments of some styrene and trans- and cis-stilbene oxides have been measured, in benzene. From these data some bond angles have been calculated and it has been deduced that in the styrene derivatives the phenyl group is in rapid interconversion about the bond with the triatomic ring.
