Organometallic reagents and catalysts continue to be of considerable importance, as illustrated in several procedures CAR-BENE GENERATION BY a-ELIMINATION WITH LITHIUM 2,2,6,6-TETRAMETHYLPIPERIDIDE l-ETHOXY-2-p-TOL-YLCYCLOPROPANE CATALYTIC OSMIUM TETROXIDE OXIDATION OF OLEFINS PREPARATION OF cis-1,2-CYCLOHEXANEDIOL COPPER CATALYZED ARYLA-TION OF /3-DICARBONYL COMPOUNDS 2-(l-ACETYL-2-OXOPROPYL)BENZOIC ACID and PHOSPHINE-NICKEL COMPLEX CATALYZED CROSS-COUPLING OF GRIG-NARD REAGENTS WITH ARYL AND ALKENYL HALIDES 1,2-DIBUTYLBENZENE. 

Note Although the name anisic acid previously was reserved for the p-m ethoxy benzoic acid , current nomenclature extends the term anisic acid to all methoxybenzoic acids, provided it is indicated which of the isomers is being described. Thus there will be o- (or 2-), m- (or 3-) and p- (or 4-) anisic acids...

Low-melting-point form (A) of 2-ethoxy-4-[N- l-(2-piperidino-phenyl)-3-methyl-l-butyl -aminocarbonylmethyl]-benzoic acid. 

Oxazolium salts are easily attacked by nucleophiles. The hydrolysis of oxazoles and benzoxazoles by hydrochloric acid has long been known. Triphenyloxazole gives benzoic acid, benzaldehyde and ammonium chloride 2-methylbenzoxazole affords o-acetamido-phenol, and 5-ethoxy-2-pentyloxazole is rapidly converted into the acylamino ester (132) by dilute hydrochloric acid at room temperature (Scheme 4). 

X-ray studies were also performed for bis(l,2,3,5-tetramethyl-4-nitropyrazolium salt [105], l-methyl-4(5)-nitro-5(4)-styrylimidazole [82], I -(/V-morpholino )-4-nitroimidazole [83], 1-sodium salt of 4-[2-[(l-methyl-5-nitro-2-imidazolyl)thio] ethoxy]-benzoic acid [106], l-methyl-4-nitro-5-chloroimidazole [107], omidazole [81], megazole [108], l-methyl-2-nitro-5-vinylimidazole [42], l-[2-(ethylsulfonyl) ethyl]-2-methyl-5-nitroimidazole (tinidazole) and one of the basic tinidazole metabolites - ammonium salt of l-[2-(ethylsulfonyl)ethyl]-4, 5-dihydro-2-methyl-4-nitroimidazole-5on [109], morpholino nitroimidazole derivatives [110, 111], l-(2-bromoethyl)-2-methyl-5-nitroimidazole [112], l-(4-chlorophenacyl)-2-methyl-... 

Dichloro-phenyl)-ethoxy]-4-methoxy-benzoic acid (0.29 mmol) dissolved in 2 ml DMF was treated with A-ethylmorpholine (1.16 mmol), 1 -pyridin-4-ylmethyl-piperazine (0.29 mmol), and 0-((cyano(ethoxycarbonyl)methylene)amino)-l, 1,3,3-tetramethyluronium tetrafluoroborate (0.3 mmol), then stirred 60 minutes at ambient temperature. The mixture was concentrated, then dissolved in CH2C12, washed three times with saturated NaHC03 solution, dried with Na2S04, and reconcentrated. The residue was purified by chromatography with silica gel using n-heptane/EtOAc, 1 1, then EtOAc, and finally EtOAc/methyl alcohol, 10 1, and 102 mg product isolated. MS ES+, m/z = 500 (M+)... 

The Step 1 product (27.6 g) was dissolved in 500 ml dioxane and added to a solution of 4-(2-methacryloyloxy)-ethoxy-benzoic acid chloride (33 g) in 100 ml dioxane and then stirred for 2 hours. The product was precipitated by pouring the solution into 2 liters of water, purified by crystallization twice from dioxane, and 30.4 g of orange-red crystals isolated with Imax = 404.5 nm (DMF) and a mp = 215-217°C. 

Dinitroanisic or Dinitrom ethoxy benzoic Acids, CHjO QHa(NOj)a-CO,H, mw 2421.4, N 11.57%. The following isomers are described in the literature ... 

PG) [benzoic acid, 3,4,5-trihydroxypropyl ester 121-79-9], although listed with the other antioxidants in 1973, is now listed in 184.1660 as an antioxidant with a maximum level of 0.015% in food. Ethoxy quin (EMQ) [quinoline, 6-ethoxy-l,2-dihydro-2,2,4-trimethyl 91-53-2] has been used in animal feeds and the carry-over in animals is limited to 5 ppm. EMQ is allowed in paprika and chili powder at 100 ppm. Nordihydroguaiaretic acid (NDGA), allowed prior to 1968, is now illegal and foods containing it are deemed adulterated. 

Monocyclic 3-ethoxy-1,2-dithiolium ions are easily hydrolyzed to the corresponding dithiolone. The same compounds are obtained with anhydrous ethanol, which is transformed into diethyl ether." With 3-ethoxy-l,2-benzodithiolium ion, hydrolysis gives only small quantities of 1,2-benzo-dithiol-3-one, the major product being 2,2 -dithiobis(benzoic) acid." Vilsmeier salts such as 26 are vinylogs of amino-1,2-dithiolium ions (27) and, accordingly, are attacked by nucleophiles. Hydrolysis of 26 is a good preparation of a-(l,2-dithiol-3-ylidene) aldehydes, as shown in the case of 28. Methanolysis may be also realized by heating in methanol. ...
