Phenyl-acetic acid ethylene

The cationic palladium(II) complex [Pd(24a)3Cl]+ of the para-isomer of 24a (M = Na) catalyzes the carbonylation of benzyl chloride in basic medium to give phenyl-acetic acid in high yields. The Pd(0) complex [Pd(24a)3], formed by reduction of [Pd(24a)3Cl]+ with CO, is asumed to be the catalytic species [93] (see Scheme 1). Palladium complexes of ligands related to 24a (M = Na) have also been employed in aqueous ethylene glycol phases as catalysts for Suzuki-type C—C cross-coupling reactions for the syntheses of substituted biphenyls (cf. Section 6.6) [97]. 

To a well stirred suspension of 9 g of sodium phenyl acetate and 2.4 g of magnesium turnings in 25 cc of anhydrous ether, a solution of 9.4 cc of isopropyl bromide in 50 cc of anhydrous ether are added. The mixture is refluxed for one hour (during which time propane is evolved) and then 5 cc of cyclopentanone in 25 cc of anhydrous ether are added dropwise. The mixture is then refluxed for one hour and poured over ice water containing some hydrochloric acid. The ether solution is separated and extracted with 200 cc of 5% sodium hydroxide. The alkaline solution on acidification gives the free acid which is filtered off, dried in a desiccator and recrystallized from a mixture of ethylene dichloride and petroleum ether. 

Castro (1964) reported that iron(II) porphyrins in dilute aqueous solution was rapidly oxidized by DDT to form the corresponding iron(III) chloride complex (hematin) and DDE, respectively. Incubation of /5,//-DDT with hematin and ammonia gave p./Z-DDD, p./Z-DDE, bis(/5-chloro-phenyl)acetonitrile, l-chloro-2,2-bis(jD-chlorophenyl)ethylene, 4,4 -dichlorobenzophenone, and the methyl ester of bis (jo-chlorophenyl) acetic acid (Quirke et al., 1979). 

Bluyssen, Fernandes and Groes (1996) identified propylene glycol ethyl ether, ethylene glycol butyl ether, ethylene glycol phenyl ether, diethylene glycol ethyl ether, acetic acid butyl (or ethyl) ester, butoxyethoxyethyl acetate in established European offices.

Thienylthioethanols were obtained in high yields by the reaction of thiophen-2-thiols with ethylene oxide.The reaction of 2,4-dinitro-3-bromothiophen with sodium dimethylthiocarbamate or sodium t-butyl-trithiocarbonate yielded (142). Decomposition of (142b) in glacial acetic acid led to a mixture of (143) and (144) in moderate yield. The reaction of thiophen-3,4-dithiol with phosgene chloride, followed by nitration, gave (145). The reaction of thiophen-2-thiol with p-(methylsulphonyl)bromo-benzene was used for the preparation of 2-thienyl p-(methylsulphonyl)phenyl sulphide.

Photodegradation of poly(acrylic acid [449, 1952] occurs by mechanisms similar to those described for poly(methacrylic acid) (cf section 3.4.2). There are several papers devoted to the photodegradation of polycarboxylic acid esters such as poly(vinyl acetate) [335-337, 519, 749, 750, 1482, 2147, 2173] (cf section 3.4.4), poly(vinyl propionate [335-337], poly(vinyl butyrate) [1480], and copolymers such as poly(acrylic acid-co-phenyl isopropenyl ketone) [1465], poly(vinyl acetate-co-ethylene [335-337,2003], poly(vinyl acetate-coethylene) blends with poly(vinyl chloride [2005] and poly(vinyl acetate-cophenyl vinyl ketone [1208, 1209].
