Procedure for 18-crown-6: http://www.orgsyn.org/Content/pdfs/pr...  

In this video I am making 1,2-bis(2-chloroethoxy)ethane using the Appel reaction with carbon tetrachloride and triphenylphosphine. This reaction is relatively uncommon nowadays due to restrictions on carbon tet, therefore I followed my own procedure which I put together from general statements online (due to its simplicity). Afterward, I used this product while following an orgsyn procedure to make 18-crown-6.
