Fluoroalkane aromatization over hot sodium oxalate

, p. 67 - 72 (1999)
Hot sodium oxalate (465°C) aromatizes perfluorodecalin to give perfluorotetralin and perfluoronaphthalene. Decomposition of solid sodium oxalate at temperatures above 450°C involves initial formation of elemental carbon that catalyzes the subsequent decomposition of oxalate, leading to the presence of an induction period in the overall decomposition reaction. Prior incipient decomposition of sodium oxalate to carbon and sodium carbonate is necessary for this reagent to effect aromatization.

Fluorination of tetralin, using potassium tetrafluorocobaltate(III) at 275-300 deg C, gave a series of compounds with bicyclodecane skeletons, as follows: -hexadecafluoro-1(6)-ene (1); tetradecafluoro-1(6),3(4)-diene (2); 3H-pentadecafluoro-1(6)-ene (3); perfluorotetraline (6) (all reported earlier); 8H-tridecafluoro-1(6),3(4)-diene (4); 3H,4H-tetradecafluoro-1(6)-ene (5); a mixture of 3H,8H- and 3H,9H-tetradecafluoro-1(6)-ene (7 and 8); 2H-undecafluorotetralin (9); 3H,4H,8H-tridecafluoro-1(6)-ene (10).The structures of all the new products (4,5,7-10) were determined by elemental analysis, protone and fluorine nmr, and mass spectrometry.Obviously, with this reagent, the residual 1(6) double bond and the β-hydrogens are the most difficult to replace.
