Novel synthetic methodology for metalloporphyrins in ionic liquid

Authorship SCIMAGO INSTITUTIONS RANKINGS

5,10,15,20-Tetraarylporphyrins undergo metalation with metal salts in the presence of reusable 1-hexyl-3-methylimidazolium bromide ([hmim][Br]) as solvent at room temperature to afford the corresponding metalloporphyrins in 80-98% yields.
