I used DMF to dissolve CSBR and PBBR2 with DMF at 90 ° C, but the amount of CSBR is a little less than the amount of PBBR2 to fully dissolve the clear solution

Whether it is DMF, DMSO, NMP, DMAC, or HMPA, although these are intangible sub -type strong polar solvents, the ability to dissolve inorganic salt or organic salt is far from compared with water. We have done a lot of similar reactions before (such as O-alkylated reactions of carboxylic acid salt, that is, esterization reaction).Or sodium salt stir in the DMF or DMSO system, whether it is normal or heated, is a translucent state, that is, it cannot be completely dissolved, and at least the solubility is still not very large.I don't know what type of reaction you are going to do?In fact, even if some reactions cannot be completely dissolved, it can be done well. If you need to be completely dissolved for your response, it is only adjusted to other intangible polarity solvents of the same type.

Similar to the solubility of sodium bromide and potassium
That is to say, it is a little dissolved, which is generally consumed in the reaction process.Copper copper, copper metharocarm, cyanide copper, etc., are not completely dissolved, but can still react
can be grinded so that salt can be scattered in the solvent with fine particles
