Since being able to make acyl chlorides, alkyl chlorides, acid anhydrides, ect is very useful, reagents like thionyl chloride and phosphorus
pentachloride are very useful. However, they are quite hard to get, especially as phosphorus cannot be easily bought in the USA. I was wondering it it
might be possible to make ie. calcium phosphide via the aluminothermic reduction of calcium phosphate, then react it with chlorine gas to produce
calcium chloride and phosphorus pentachloride. However, I am somewhat worried about the phosphide reacting with atmospheric moisture to form
phosphine, or it making smoke during the aluminothermic reduction which contains dangerous amounts of phosphide. Should I try to do this or is it too
dangerous?

You could use cyanuric chloride instead, which is much less hazardous than either of those reagents.

Where can you get cyanuric chloride?
