The fresh 3,5-dinitro benzoylchloride (2.30 g, 0.01 mol) dissolved in 10 mL of C[H.sub.2][Cl.sub.2] (MDC) was added dropwise to a solution containing a mixture of tryptamine (1.60 g, 0.01 mol) and triethylamine (5.0 mL) in 20 mL of C[H.sub.2][Cl.sub.2] in an ice bath.
Separation was accomplished by using buffers: A (sodium acetate, pH 6.4, 5,000 ppm ethylenediaminetetraacetic acid (EDTA), triethylamine (1:2,000) and 6%, v/v, acetonitrile) and B (60%, v/v, acetonitrile and 5,000 ppm EDTA).

The catalytic Kharasch reaction of [alpha]-pinene, [beta]-pinene, limonene, limonene oxide, and valencene was studied using the iron acetylacetonate as catalyst and triethylamine as cocatalyst.
L-Aspartic acid (le) (7.98 g, 0.060 mol) and triethylamine ([NEt.sub.3]) (12.14 g, 0.12 mol) were dissolved in distilled water (250 mL), and Boc-Gly-ONSu (13.61 g, 0.050 mol) dissolved in 1,4-dioxane (250 mL) for 4 h was added to the solution.
The mobile phase was a solution of HPLC-grade methanol, water, glacial acetic acid and triethylamine at a ratio of 1600:400:05:1 (RAO et al., 2004) which was injected into the system at a flow rate of 0.8ml/min after being filtered through a 0.45 mm membrane filter.
The compounds which are used depend on the surface activity of the silica/alumina coating and are typically triethylamine (TEA), trimethylol propane (TMP), trimethylol ethane (TME), and low molecular weight polyethylene wax (PE).
