Reaction Steps

This invention concerns the compound oxybis(4,1-phenylene(2-oxo-2,1-ethanediyl)) thiocyanate, hereinafter referred to as "Compound", corresponding to the formula ##STR1## Compound is prepared by reacting diphenyl oxide with chloroacetyl chloride in the presence of alumnium chloride in carbon disulfide reaction medium, whereby 1,1'-(oxydi-4,1-phenylene)bis[2-chloroethanone] is formed. The latter is then reacted with alkali metal thiocyanate, advantageously potassium thiocyanate, in acetone as reaction medium to form Compound.
