(2-Phenyl-4-methylthiazol-5-yl)-alpha-phenylmethyl acetate 2 undergoes
thermal elimination of acetic acid to give the o-quinodimethane 3. In
solution this can be intercepted in Diels-Alder reactions but under f
lash pyrolytic conditions naphthalene-2-thiol is formed by electrocycl
isation and fragmentation.
