Occurrence of alachlor environmental degradation products in groundwater
Potter,Carpenter
, p. 1557 - 1563 (2007/10/03)
Groundwater samples collected beneath a Massachusetts corn field were analyzed by gas chromatography/mass spectrometry. In addition to alachlor, 20 compounds were detected whose EI and CIMS data indicated that they were derived from alachlor, presumably via environmental degradation. Structural assignments were confirmed for six of these compounds by analysis of standards. They were among 10 alachlor-related compounds that were synthesized by use of either the parent compound or 2,6-diethylaniline as starting material. -from Authors
Comparative metabolism and elimination of acetanilide compounds by rat

1. 14C-labelled propachlor, alachlor, butachlor, metolachlor, methoxypropachlor and some of their mercapturic acid pathway metabolites (MAP) were given to rat either by gavage or by perfusion into a renal artery MAP metabolites were isolated from bile and urine. 2. Rat gavaged with propachlor and methoxypropachlor eliminated 14C mostly in urine, whereas rat gavaged with alachlor, butachlor and metolachlor eliminated 14C about equally divided between urine and faeces When bile ducts were cannulated, the gavaged rat eliminated most of the 14C in bile for all compounds The amount of 14C in bile from the propachlor-gavaged rat was less than that for the other acetanilides, with the difference being in the urine 3. The mercapturic acid metabolites 2-methylsulphinyl-N-(1-methylhydroxyethyl)-N-phenylacetamide and 2-methylsulphinyl-N-(1-methylmethoxyethyl)-N-phenylacetamide were isolated from the urine and bile of the methoxypropachlor-gavaged rat 4. Bile was the major route for 14C elimination when MAP metabolites of alachlor, butachlor and metolachlor were perfused into a renal artery Urine was the major route for 14C elimination when MAP metabolites of propachlor and methoxypropachlor were perfused Mercapturic acid conjugates were major metabolites in bile and urine when MAP metabolites were perfused 5. We conclude that alkyl groups on the phenyl portion of the acetanilide causes biliary elimination to be favoured over urinary elimination

Radical addition of 1,4-dioxane to aldimines proceeds at the imidyl carbon atom with formation of asymmetrical secondary amines.By the method of competitive kinetics we have determined the relative activities of Schiff bases and have found that the regiod
Revisitation of Formaldehyde Aniline Condensation. VIII. - Monomeric N-Methylene Anilines

A convenient, high yield "dry" method of synthesis of monomeric N-methyleneanilines (6a-i) and the characterization of the products by m.s., 1H- and 13C-n.m.r. and i.r. are reported, improving previous procedures and describing new compounds.It appeared that the existence of monomeric N-methyleneanilines is stricly related to the presence of enough steric hindrance to oligomerization by substituents in ortho positions.Moreover, some addition products of formaldehyde to an amine and its corresponding imines are tentatively identified on the basis of the observed mass spectrum of the whole reaction mixture.The reaction products of formaldehyde with 2,6-dimethylaniline (1a) provided an example of a mobile equilibrium between monomeric and trimeric imine.
