Wolffs equilibrium form

Figure 4.6. Wolffs equilibrium form [10]. AB composition ofwurtzite type. The equilibrium form changes depending on the ionicity in the A-B bonding.

In Fig. 4.6, the result obtained by the Wolff construction illustrates how the equilibrium form of a crystal consisting of atoms A and B will change depending on the changing ionicity of the A-B bond.

Hopkinson in 1973175 investigated the Wolff rearrangement of diazo-ketones and a-diazo-esters to form ketens. In particular, an MBS was used to investigate the equilibrium [equation (11)]11 between the parent oxiren (7) and the isomer formyl-...
