Solvolyses of 1-14C-2-phenylethyl tosylate (1-OTs-1-14C) were carried out in HOAc and H2O solvent systems with or without added NaN3. In the absence of added azide ion, the products obtained from a given solvent mixture of HOAc–H2O, 1-OAc-14C, and 1-OH-14C, showed essentially the same extent of rearrangement of the 14C-label from C-1 to -2. In the presence of added azide ion, the rearrangement in the 1-N3-14C was less than that found in the 1-OAc-14C or 1-OH-14C. The results are interpreted in terms of concurrent direct displacement to give product and product formation from the ethylenephenonium ion.

Die Solvolyse des Tosylats (I) mit Wasser/Essigsäure‐Gemischen wechselnder Zusammensetzung führt zu den Solvolyseprodukten (III) und (IV) sowie in Anwesenheit von Na‐azid zu der zusätzlichen Bildung von 2‐Phenyl‐äthylazid.

Die Trifluoracetolyse der Titelverbindungen führt zur Bildung aller isomerer Ester, wobei die Alkyl‐(2)‐trifluoracetate die Hauptprodukte darstellen.
