Revised mechanism of Boyland-Sims oxidation.

New computational insights into the mechanism of the Boyland-Sims oxidation of arylamines with peroxydisulfate (S(2)O(8)(2-)) in an alkaline aqueous solution are presented. The key role of arylnitrenium cations, in the case of primary and secondary arylamines, and arylamine dications and immonium cations, in the case of tertiary arylamines, in the formation of corresponding o-aminoaryl sulfates...

N-demethylation of p-chloro-N-methylaniline catalyzed by subcellular fractions from the avocado pear (Persea americana).

Subcellular fractions from the avocado pear ( Persea americana) catalyzed formation of p-chloroaniline from p-chloro-N-methylaniline. Fractions prepared by centrifugation of avocado homogenates at 20, 000g for 20 min formed p-chloroaniline (2900 +/- 500 pmol min-1 mg protein-1) with an NADPH-generating system. p-Chloroaniline formation required reduced pyridine nucleotide (NADPH was 6-7 times m...

Pharmacokinetic study of p-chloronitrobenzene in humans suffering from acute poisoning.

The pharmacokinetics of p-chloronitrobenzene (p-CNB) in human subjects suffering from acute poisoning was studied from the urinary excretion of p-CNB metabolites. The time course for excretion of five metabolites--2-chloro-5-nitrophenol,N-acetyl-S-(4-nitrophenyl)- L-cysteine, 2,4-dichloroaniline, p-chloroaniline, and 2-amino-5-chlorophenol-were determined by reversed-phase HPLC analysis of urin...

Reactions of 3,5-Dimethyl-1,2,4,3,5-trithiadiborolane with Secondary Amines: Formation of Diorganylamino(sulfhydryl)boranes*

The 1 : 1 reaction of 3,5-dimethyl-1,2,4,3,5-trithiadiborolane, 3, with dimethylamine in diethyl ether yielded a mixture of compounds from which only MeB(NMe2)SH, 7, could be separated. In the 1:2 reaction, insoluble Me2NH(MeB(S2)2BMe)HNMe2, 10, could be isolated besides 7 and small amounts of MeB(NMe2)2. In the presence of NMe3 the bis(methyl-dimethylamino-boryl)sulfide, 7 was obtained in good...
