Many of these salts melt or sublime before or during decomposition and reaction temperatures generally increase with molar mass. Thermal analyses for a selection of ammonium carboxylates have been given by Erdey et al. [915] who conclude that the base strength of the anion increases with temperature until it reaches that of NH3. Decompositions of ammonium acetate (>333 K) and ammonium oxalate (>473 K) proceed through amide formation. Ammonium benzoate and ammonium salicylate sublime (>373 K) without decomposition but ammonium citrate decomposes (>423 K) to yield some residual carbon.

The effect of structural variation and the use of different caboxylate salts as cocatalysts was investigated by Pietikainen . The epoxidation reactions were performed with the chiral Mn(III)-salen complexes 173 depicted in Scheme 93 using H2O2 or urea hydrogen peroxide as oxidants and unfunctionalized alkenes as substrates. With several soluble carboxylate salts as additives, like ammonium acetate, ammonium formate, sodium acetate and sodium benzoate, good yields (62-73%) and moderate enantioselectivities (ee 61-69%) were obtained in the asymmetric epoxidation of 1,2-dihydronaphthalene. The results were better than with Ai-heterocycles like Ai-methylimidazole, ferf-butylpyridine.

C—C—O—C+N. The formation of oxazoles from a-acyloxy ketones and ammonium salts was discovered in 1937 when it was found that treatment of benzoin benzoate with ammonium acetate in hot acetic acid gave triphenyloxazole in excellent yield. It has been shown that the reaction proceeds by way of intermediate enamines (equation 113). The synthesis is quite general and it is only.limited by the difficulty of obtaining the starting keto esters, particularly formates. The latter are probably intermediates in the preparation of cycloalkenooxazoles from acyloins and formamide in hot sulfuric acid (equation 114). Another variation is to heat a mixture of an a-bromo ketone, the sodium salt of a carboxylic acid and ammonium acetate in acetic acid (equation 115).

Sodium benzoate and potassium soibate preservative levels in foods (juices, soda, sauces) were determined using a Cig column (2 = 225 nm for benzoate, 255 nm for sorbate) and a 90/10 water (0.3 g ammonium acetate/L to pH 4.2 with acetic acid)/acetonitrile mobile phase [900]. Peaks were somewhat broad but well resolved and eluted in <15 min. Linear curves were reported as 2.5-200 mg/L with detection limits of 1 mg/L.

The SrjjI reaction of o-iodo and o-bromo-benzoate salts with CHjCOMe ion affords the substitution product ca. 78% yield), which upon acid treatment with toluene p-sulphonic acid gives the corresponding isocoumarin 15 (90%) (Scheme 4). Benzazepines 16 can be produced upon ammonium acetate treatment of the substitution compound obtained in the reaction of (o-iodophenyl) acetic acid derivatives with enolate ions from ketones ( CHjCOR, R = Me, i-Pr, t-Bu 50, 60, and 56%, respectively) (Scheme 5)." ...

This is an Sn2 process, since inversion is found at R. Another good leaving group is NTS2 ditosylamines react quite well with acetate ion in dipolar aprotic solvents RNTs2 4- OAc — ROAc. Ordinary primary amines have been converted to acetates and benzoates by the Katritzky pyrylium-pyridinium method (p. 447). Quaternary ammonium salts can be cleaved by heating with AcO in an aprotic solvent. Oxonium ions can also be used as substrates RsO -f R COO —> R COOR R2O.

To a solution of 0.20 g of (-)-3a,5a-dihydroxy-2p-(3-oxo-trans-l-octenyl) cyclopentane-la-acetic acid y-lactone 3-benzoate in 15 ml of tetrahydrofuran at -78°C under nitrogen was added dropwise 3 ml etheral solution 3 M methylmagnesium bromide. The solution became heterogeneous after 2 hours, to the mixture was added 10 ml of saturated aqueous ammonium chloride and then ether and water. Organic extract was washed with brine, dried over sodium sulfate, and evaporated to give 0.21 g of (-)-3a,5a-dihydroxy-2p-[(3RS)-3-hydroxy-3-methyl-trans-octenyl] cyclopentane-la-acetic acid y-lactone 3-benzoate as a colorless oil [a]D = -80° (c 1.0, CHCI3).
