Abstract The preparation of the ditertiary phosphines 2,11‐bis (di‐ m ‐tolylphosphinomethyl)benzo [ c ]phenanthrene ( 1b ), 2,11‐bis (di‐ p ‐anisylphosphinomethyl)benzo‐[ c ]phenanthrene ( 1c ), 2,11‐bis (di‐ m ‐trifluoromethylphenylphosphinomethyl) benzo‐[ c ]phenanthrene ( 1d ), 2,11‐bis (dicyclohexylphosphinomethyl)benzo [ c ]phenanthrene ( 1e ) and 2,11‐bis [di‐( t ‐butyl)phosphinomethyl]benzo [ c ]phenanthrene ( 1f ), by a combination of synthetic routes is described.
