要旨:
Flash vacuum pyrolysis of the ester 1,3,4,5,6,7,8-heptafluoro-2-naphthyl
propynoate (6) at 550 °C/0.01 mmHg gave three products: 3 and 4
by an overall decarbonylation reaction. and 5 by a further
decarbonylation of 3 and/or 4. Isomerisation of 6 to 2-fluoropropynyl
2-naphthoate 8 by a Diels-Alder/retro-Diels-Alder sequence followed by
decarbonylation and a series of 1,2-fluorine shifts offers a
rationalisation for the formation of the products.
