| Abstract: | Phosphatriptycene (1) is prepared by cyclizing 9-(o-chlorophenyl)-9,10-dihydrophosphaanthracene (6) with an excess of lithium diisopropylamide in ether. Its structure is confirmed by its 13C-NMR spectrum. In nucleophilic reactions 1 is less reactive than triphenylphosphine. The nature of the bonding in quaternary phosphonium salts of 1 is discussed. |
