The spiriphosphorane (1b) (5-phenyloctamethyl-1,4,6,9-tetraoxa-5-phosphaspiro<4.4>nonane) undergoes acid-catlysed ligand exchange 107 times faster than acid-catalysed hydrolysis; these two processes have a common phosphonium ion intermediate which has a large preference for reaction with its internal hydroxy group over capture by external water moleczule.
