i need to make potassium cyanide and i found a equalition and it says heat till 650 celcius.
                     3K4[Fe(CN)6]−→Δ12KCN+Fe3C+5C+3N
what should i do. Just put this ''3K4[Fe(CN)6]'' to a pan an put it on to oven and heat it?

I dont think so, alkyllithium can do this but not grignard.
To my surprise there appears to be a synthetically useful exchange reaction:  https://onlinelibrary.wiley.com/doi/full/10.1002/anie.200300579

thanks for reply. i dont mind if it would be my last experiment or not. i live in a country that potassium cyanide is illegal to buy but potassium ferrocyanide is legal. i wont kill someone. i want to suicide but i want peaceful death like sleep. i dont have guts to try the other terrifiying methods. pls help me i dont have courage to live anymore.

It you have no knowledge, then you shouldnt do anything. Cyanides are very poisson stuff. Maybe it would be your last experiment. The other question for what do you need it?

The butenyl-Grignard you have in the scheme is also commercially available.
