A selective and sensitive method for the preconcentration, separation, and determination of palladium with flame atomic absorption spectrometry using 4,15-bis[(4-methylphenyl)sulfonyl]-20,21-dinitro-2,3,4,5,6,7,9,10,12,13,14,15,16,17-tetradecahydro- 8,11-ethano-1,18,4,8,11,15-benzodioxa tetraaza cycloicosine (TNACIN) on XAD-2010 was developed. TNACIN-Pd(II) complex formed acidic aqueous solution (0.075-0.100 M HNO3) was accumulated on XAD-2010 and then eluted with 1 M HCl in acetone. The effects of some analytical parameters including pH, TNACIN amount, sample volume, eluent type, and concentration, sample flow rate and matrix ions were studied for optimization of the method. Detection limit and precision were calculated for Pd(II). This method was also verified with CRM and internal standard, and satisfactory results were obtained.

The reaction of 4-(1,3,2-benzodioxaphosphol-2-yloxy)-3-tert-butylpent-4-en-2-one with hexafluoroacetone

Catalytic (ZnCl2, Et3N) phosphorylation of tert-butylacetyl-acetone with 2-chloro-1,3,2-benzodioxaphosphole unexpectedly occurs with elimination of proton from the methyl group and leads to vinyloxyphosphole derivative, viz., 4-(1,3,2-benzodioxa-phosphol-2-yloxy)-3-tert-butylpent-4-en-2-one. Its reaction with hexafluoroacetone gives a cage phosphorane as a result of subsequent chemoselective[4+2]- and [3 + 2]-cyclo-additions with stereoselectivity above 95%.

KINETICS, MECHANISMS, AND SYNTHESIS STUDIES OF RING-OPENING-CLOSING ALTERNATING COPOLYMERIZATION

The present paper describes the ring-opening-closing alternating copolymerization of cyclic phosphonites (2-phenyl-1,3,2-dioxaphospholane (1a), 2-phenyl-1,3,2-dioxaphosphorinane(1b), 2-phenyl-1,3,2-dioxaphosphepane(1c), and 2-phenyl-4H-1,3,2-benzodioxa phosphorin-4-one(1d) with muconic acid(2a), succinaldehyde(2b), glutaraldehyde(2c), adipinaldehyde(2d), o-phthalaldehyde(2e), acrylic anhydride(2f), methacrylic anhydride(2g), N-methyl diacrylamide(2h), and N-methyldimethacrylamide(2i). The reaction of a 1:1 monomer feed ratio, explained by a mechanism of propagation via zwitterion intermediates, proceeds without any added catalyst to give an alternating copolymer 3 involving ring-opening of 1 and ring-closing of 2. The structure of copolymer 3 was determined by H-1, C-13 NMR, P-31 NMR and IR spectroscopies as well as elemental analysis.

Different role of carboxylesterases in toxicity and tolerance to paraoxon and DFP

The contribution of carboxylesterase (CarbE) to toxicity and tolerance to the organophosphorus anticholinesterases; (OP-antiChE) paraoxon (diethyl p-nitrophenyl phosphate) and DFP (diisopropylphosphorofluoridate) was investigated in rats. Daily injections (20 days) of paraoxon (0.33 mu mol/kg) or DFP (2.72 mu mol/kg) reduced AChE activity in brain to 29 or 16% and in diaphragm to 58 or 54%, respectively. The animals tolerated an accumulated 6-fold LD50 dose and survived an LD90 dose of carbachol, indicating tolerance to this cholinergic agonist. A single dose of paraoxon or DFP significantly reduced CarbE activity of plasma, lung and liver. After paraoxon, rapid recovery was seen of plasma and liver CarbE while recovery after DFP was much slower. Daily pretreatment with the CarbE inhibitors CBDP (2-[o-cresyl]-4H-1,2,3-benzodioxa- phosphorin-2-oxide) (7.22 mu mol/kg, s.c.) or iso-OMPA (tetraisopropylpyrophosphoramide) (8.76 mu mol/kg, i.p.), followed by paraoxon (0.33 mu mol/kg, s.c.) 30 min later, prevented the development of tolerance to paraoxon and potentiated its toxicity. Rats died on day four of the combined treatment. The CarbE inhibitors neither potentiated the DFP toxicity, nor prevented tolerance development to DFP. We conclude that rat plasma CarbE provides a significant protection against paraoxon toxicity because its rapid reactivation can reduce the toxicity of repeated paraoxon applications and thus contribute to tolerance development. This same mechanism does not apply to DFP toxicity, as inhibition of CarbE of plasma, liver and lung neither potentiated its toxicity, nor prevented tolerance development. These findings confirm previous observations that CarbE detoxification is of greater importance for highly toxic OP-antiChEs such as nerve agents and paraoxon than for less toxic ones such as DFP.
