thermal elimination of acetic acid to give the o-quinodimethane 3. In solution this can be intercepted in Diels-Alder reactions but under flash pyrolytic conditions naphthalene-2-thiol is formed by electrocyclisation and fragmentation.
对α-(2-苯基-4-甲基噻唑-5-基)-α-苯基甲基乙酸酯2进行乙酸的热消除,得到邻喹啉二甲烷3。在溶液中,这可以在Diels-Alder反应中截获,但在快速热解条件下,萘2-硫醇通过电环化和断裂形成。
