- Silver(I) ion-mediated desulfurization-condensation of carbon disulfide with some hydroxyl compounds
-
The title reaction with ethanol and phenol gave tetraethyl and tetraphenyl orthocarbonate, respectively, in good yields. Diols, such as benzene-1,2-dimethanol, wieso-hydrobenzoin, and cathecol, afforded spiro orthocarbonic acid esters. In the same manner, 2-anilinoethanol, N-methylanthranilic acid, and salicylic acid led to some novel spirobicycles.

- Method for making diaryl carbonate
-
Diaryl carbonate is prepared by hydrolysis of a tetraaryl orthocarbonate in the presence of an acid catalyst. The tetraaryl orthocarbonate is synthesized by a reaction between carbon disulfide and a cuprous phenate; the cuprous phenate can be made from cuprous chloride and the corresponding alkali metal phenate. The process may be integrated with recycle of by-products.
