... STUDIES /OF PHENYL (14)C PROPANIL ON PLANTS/ INDICATED THAT A MAJOR PORTION OF 3,4-DICHLOROANILINE ... MOIETY WAS COMPLEXED WITH POLYMERIC CELL CONSTITUENTS, MAINLY LIGNIN.
OATS TOOK UP & TRANSLOCATED WITHIN 6 WEEKS ONLY 0.7% OF THE SOIL-BOUND (14)C-LABELED 3,4-DICHLOROANILINE. UPTAKE FROM SOLUTION WAS 2.2 TO 2.5%. 3,4-DICHLOROANILINE WAS ADDED TO SOIL AT 1 PPM, AND AFTER 16 WEEKS THE NONBOUND FRACTIONS WERE REMOVED WITH WATER & ORGANIC SOLVENTS, FOLLOWED BY PLANTING OF THE OAT. THERE WERE ONLY SLIGHT DIFFERENCES IN RESULTS BETWEEN THE TWO SOIL TYPES (HUMUS-RICH GLEY AND PARABROWN SOILS) STUDIED.
THE CONJUGATION OF PESTICIDES WITH NATURAL MACROMOLECULES IN ANIMALS, PLANTS AND SOIL ORGANIC MATTER WAS REVIEWED. WHEN RICE PLANTS GROWN HYDROPONICALLY WERE TREATED WITH (14)C-3,4-DICHLOROANILINE, GREATER THAN 40% OF THE (14)C WAS FOUND IN THE ROOTS IN ISOLATED LIGNIN FRACTIONS. CHLOROANILINES MAY BE BONDED COVALENTLY TO LIGNIN VIA 1,6 ADDITION TO A QUINONE METHIDE INTERMEDIATE DURING THE LIGNIN SYNTHESIS.

吸收、分配和排泄
一旦进入人体,3,4-二氯苯乙酸主要在尿液中排出。
Once ingested into the human body, 3,4-DCA is excreted mainly in the urine.
Using hairless rat skin maintained in a Franz diffusion cell, the percutaneous penetration of four aromatic amines: para-chloroaniline, meta-trifluoromethylaniline, dichloro-3,4-aniline and dichloro-3,5-aniline were studied. The purpose of the studies was to determine the permeation parameters (rate of permeation, permeability rat constant) in order to compare the rate of absorption of the four amines. The results show that the four amines penetrate significantly across the skin, but with different rates. 10 h after in vitro application (2 mg/cm sq), the extent of permeation was para-chloroaniline meta-trifluoromethylaniline > dichloro-3,4-aniline > dichloro-3,5-aniline.
Development of a novel protocol for chemoselective deprotection of N/O-benzyloxycarbonyl (Cbz) at ambient temperature
摘要:
A novel protocol for the deprotection of N-benzyloxycarbonyl and O-benzyloxycarbonyl groups by nickel boride generated in situ from NaBH4 and NiCl(2)6H(2)O in methanol at room temperature has been developed to give the corresponding amines and phenols. This protocol is chemoselective as groups like chloro, bromo, amide, ester, pyridine, and tert-butyloxycarbonyl moiety are unaffected under these conditions. The deprotection has also been validated in gram scale reactions, to establish the wider appropriateness of this protocol.

for the synthesis of selectively N-substituted tetra- and pentamethylenediamines 1 (n = 4,5) is described. The method uses N-substituted ω-haloalkanamides 2 as precursors and involves the microwave-promoted conversion into ω-azidocarboxamides 3 and later the reduction of both azido and carboxamide groups with diborane.
Several five-membered heterocycles having a phenylazo substituent, 3-phenylazotetronic acids (2a-n), 3-phenylazotetramic acids (4a-i), 4-phenylazo-5-isoxazolinones (6a-g, 8a-f) and 5-phenylazo-4-thiazolidinones (10a-f, 12a-e), were synthesized and tested for antimicrobial activities. Tetronic acid and tetramic acid derivatives (2 and 4) inhibited the growth of gram-positive bacteria. 5-Isoxazolinone and 4-thiazolidinone derivatives (8 and 10) showed inhibitory activities against fungi as well as bacteria.
