The Solvolysis of 5,5-Diphenylcyclononyl p-Toluenesulfonate. A Reinvestigation

Reinvestigation of the acetolysis of 5,5-diphenylcyclononyl tosylate (1) has confirmed the absence of any transannular processes and deamination of the corresponding amine 16 gave a similar resuit. Trifluoroacetolysis of 1 caused extensive transannular hydride migration but no phenyl migration. The former may be due to secondary acid-catalyzed rearrangements.
