1,3,4,5,6,7,8-Heptafluoro-2-naphthyl prop-2-ynyl ether (5) and boiling isopropylbenzene gives 1,3,4,5,6,7,8-heptafluoro-1-(propa-1,2-dienyl)naphthalen-2-one (9) and two isomeric 2-(isopropylbenzyl)-4,5,6,7,8,9-hexafluoronaphthofurans (11).Di-(4,5,6,7,8,9-hexafluoronaphthofuran-2-ylmethyl) ether (17) and bis-(4,5,6,7,8,9-hexafluoronaphthofuran-2-yl)methane (18) are formed from (5) in CF2ClCFCl2 at 137 deg.The solvolysis of 2-fluoromethyl-4,5,6,7,8,9-hexafluoronaphthofuran (10) in water at 145-156 deg yields (17) (2percent), (18) (37percent) and 4,5,6,7,8,9-hexafluoronaphthofuran-2-ylmethyl alcohol (19) (13percent).Pentafluorophenyl prop-2-ynyl ether (1) reacts in either C6F6 or CF2ClCFCl2 at 140 deg to give di-(4,5,6,7-tetrafluorobenzofuran-2-ylmethyl) ether (15).The major product from the solvolysis of 2-fluoromethyl-4,5,6,7-tetrafluorobenzofuran (2) in water at 140-142 deg is 4,5,6,7-tetrafluorobenzofuran-2-ylmethyl alcohol (16) (87percent) accompanied by (15) (2.5percent).
