In the "Wacker KRV - Ketone's Guide to Wacker-powered Production of MDP2P using methanol" synth, it says
"In this case, we'll be using cupric chloride (CuCl2). Copper chloride (CuCl) cannot be used in the procedure outlined here as it does not dissolve in methanol (MeOH) or ethanol (EtOH) and thus does not form the required complex."
Swims question being thus, Is CuCl2-2H20 interchangeable with the required chem in the synth? since its the same thing, only with two H20 molecules attached (dihydrate). thanks
