Hexafluoroisopropylidene-unit-containing copoly(ether ketone)s and copoly-(sulfide ketone)s are also synthesized by reacting mixtures of 2,2-bis(4-carboxy-phenyl)-1,1,1,3,3,3-hexafluoropropane (15) and 2,2-bis(4-carboxyphenyl)-propane (16) with diphenyl ether or diphenyl sulfide in PPMA, respectively (Scheme 10).18... 

Crystallinity of these hexafluoroisopropylidene-unit-containing poly(ketone)s is low except for poly(sulfide ketone) (13). The water contact angle for the fluorine-containing poly(ketone) films is high, being 98° for poly(ether ketone) (11), from 2,2-bis(4-carboxyphenyl)-l,l, l,3,3,3-hexafluoropropane(15) and 96° for poly(sulfide ketone) (13) from 15, whereas it is 78° for poly(ether ketone) from 2,2-bis(4-carboxy-phenyl)propane (16) and 74° for the poly(sulfide ketone) from 16. This result indicates that the substitution of isopropylidene units of poly-(ketone)s with hexafluoroisopropylidene units has a remarkable effect on the surface properties of poly(ketone) films. 

The flash vacuum thermolysis of 4-hydroxy-2,5-diphenyl-l,3-oxazin-6-one resulted in carboxy(phenyl)ketene and benzonitrile as the major and benzoyl isocyanate as the minor product. This was interpreted in terms of the influence of the tautomeric forms on the thermal fragmentation pathways <2007JOC1399>.

B. - o-Carboxy phenyl) propionic acid. In an open 1-1. widemouthed round-bottomed flask are placed 18 g. (0.094 mole) of 0-carboxycinnamic acid and 550 ml. of 10% sodium hydroxide solution. The mixture is warmed to 90° (Note 8) on a steam bath and stirred mechanically. The steam bath is then removed while 54 g. (Note 9) of nickel-aluminum alloy (Raney catalyst) powder is added through the open neck of the flask in small portions (from the end of a spatula) at frequent intervals (Note 10). When addition of the alloy is complete (about 50 minutes), the mixture is stirred and maintained at 90-95° for 1 hour by warming on a steam bath. Distilled water is added as needed to maintain the total volume at approximately 550 ml. The hot mixture is filtered with suction, and the metallic residue is washed with 50 ml. of hot 10% sodium hydroxide solution and two 50-ml. portions of hot water in such a manner that the solid is always... 

The filtrate, either on concentration under reduced pressure or upon dilution with water, fails to yield more o-carboxycinnamic acid, but a crystalline by-product, presumably 4-(o-carboxy-phenyl)-5,6-benzocoumarin,2 may be encountered in small yield.
