SYNTHESE DE NOUVEAUX SELS DE TETRAPHOSPHONIUM MACROCYCLIQUES
Vincens, Maurice,Grimaldo Moron, Jose T.,Pasqualini, Roberto,Vidal, Michel
, p. 1259 - 1262 (2007/10/02)
A one step synthesis of tetraphosphonium salts of the saturated 5 and ethylenic 3 macrocycles containing C-C bridges has been carried out in good yield.The cleavage of the carbon bridges during basic hydrolysis is highly regioselective.
