Abstract
Flash vacuum pyrolysis of
2,2-dimethyl-5-(2?-methylbenzylidene)-1,3- dioxan-4,6-dione (1) at 420-620? gives
2-naphthol in 95-100% yield. The reaction probably involves an intermediate 2- methylbenzylideneketene,
which undergoes consecutive [1,5] hydrogen migration and cyclization reactions.
Substituted 2-naphthols and a phenol (biphenyl-3-ol) have been synthesized in a
similar way.
