which inorganic carbonate salt can dissolve in DMF?

I tried sodium and potassium carbonate and had little luck. Anyone know where to find the solubility data of inorganic salt in DMF?Thanks.

Sodium and potassium carbonate WILL dissolve in DMF. The best way to dissolve them is to... a) dry the solid inorganic salt in an oven (> 100 degrees C) overnight. b) pulverize the powder and grind several minutes with mortal and pestle. c) sonicate the mixture for several minutes...
