The simple phosphonium salts 4 and 5 have been fully characterised for the first time and are found by NMR spectroscopy to exist in CDC13 solution mainly as the E and Z enol structures b and c. The salt 6 exists as a mixture of the keto form a and one enol form assumed to be b. Similarly the bis(pho
