Dillon, K. B. and Monks, P. K. and Olivey, R. J. and Karsch, H. H. (2004) 'The identification of some novel four-membered ring cyclic triphosphenium ions in solution.', Heteroatom chemistry., 15 (6). pp. 464-467.
The first four-membered ring cyclic triphosphenium ions with carbon substituents (methyl or cyclohexyl) on the outer phosphorus atoms have been identified in solution by P-31 NMR spectroscopy. The cyclohexyl derivative in the presence of [SnCl6](2-) as counterion was stable enough for methylation by methyl triflate to be carried out.
