Normally DMF is seems to be the best solvent for my reactions. But the main problem with solvent is its dryness. Commercially available DMF is not economic. So I have to make dry DMF in my lab.
Most of the time in order to check the feasibility of reaction we always seeks help from computational methods. Is it possible to check theoretical probability of a reaction through computational...
