Pyrolysis of bicyclo[2.2.1]heptane-2-thiols: evidence for a carbene intermediate in a thermal hydrogen sulphide elimination
Abstract
Pyrolysis of endo- and exo-bicyclo[2.2.1]heptane-2-thiols yields tricyclo[2.2.1.02,6]heptane and bicyclo[2.2.1]hept-2-ene via competing carbene and radical mechanisms.
