Transformations Of The Bicyclonon-3-enyl Carbocation With The Charge At The C7 Atom

Nigmatova, V. B.,Zaitsev, Yu. V.,Anfilogova, S. N.,Pekhk, T. I.,Belikova, N. A.

, p. 727 - 732 (2007/10/02)

7-Methyl-cis-bicyclonon-3-en-7-ol and the tosylate of cis-bicyclonon-3-en-7-ol were synthesized.It was found that the bicyclonon-3-ene carbonium cation formed intermediately during dehydration of the alcohol and during solvolysis of the tosylate does not undergo transannular cyclization.It is stabilized with the ejection of a proton, leading to bicyclononadienes.
