An amine protecting group deprotectable under nearly neutral oxidative conditions

Beilstein Journal of Organic Chemistry, 2018
The 1,3-dithiane-based dM-Dmoc group was studied for the protection of amino groups. Protection was achieved under mild conditions for aliphatic amines, and under highly reactive conditions for the less reactive arylamines.

Biodegradation of Carbamates

Water Science and Technology, 1988
A carbofuran-metabolizing Pseudomonas sp. was investigated for its capability to degrade some other toxic carbamates and its effectiveness as a decontaminant for carbamate-polluted water samples. The organisms degraded both aldicarb and carbaryl. It also decontaminated carbofuran-fortified water samples from various sources in the absence of additional

Koordinative Ringöffnungspolymerisation von Limonencarbamat zur Phosgen‐ und Isocyanatfreien Polyurethan‐Synthese

Angewandte Chemie, EarlyView.
In dieser Studie wird ein phosgen‐ und isocyanatfreier Ansatz zur Herstellung von Polyurethanen unter Verwendung von (R)‐Limonen als biobasiertem Rohstoff vorgestellt. Durch Ringöffnungspolymerisation (ROP) wird Limonencarbamat (LU) mit hoher Effizienz in Polyurethan (PLU) umgesetzt.

Crystal structures of 4-chlorophenyl N-(3,5-dinitrophenyl)carbamate and phenyl N-(3,5-dinitrophenyl)carbamate

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compounds, C13H8ClN3O6, (I), and C13H9N3O6, (II), differ in the orientation of the two aromatic rings. In (I), they are essentially coplanar, making a dihedral angle of 8.2 (1)°, while in (II), they are inclined to one another by 76.2 (1)°. The

Experimental hut evaluation of bednets treated with an organophosphate (chlorpyrifos-methyl) or a pyrethroid (lambdacyhalothrin) alone and in combination against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes [PDF]

, 2005
BACKGROUND: Pyrethroid resistant mosquitoes are becoming increasingly common in parts of Africa. It is important to identify alternative insecticides which, if necessary, could be used to replace or supplement the pyrethroids for use on treated nets ...

Insertion of carbon dioxide and isocyanide into tantalum-amide and tantalum-methyl bonds [PDF]

, 2001
The methyl–amide complex [TaCp*(NtBu)Me(NMe2)] (1a) was isolated by reaction of the chloro–methyl [TaCp*(NtBu)MeCl] complex with LiNMe2. Reaction of the mono-amide compounds [TaCp*(NtBu)XY] (X=NMe2, Y=Me (1a); X=NHtBu, Y=Me (1b), Cl (1c)) with CO2 gives ...

Metabolite Formation of Pesticide Isoprocarb in Coffee Beans During Short-Term Storage and Condition

Jurnal Kimia Sains dan Aplikasi
Isoprocarb (IPC) is one of the most important carbamate pesticides for white flea control in coffee plants. The prevalence of isoprocarb pesticide residues in coffee, i.e., green coffee beans, is a cause for concern. Green coffee beans were intentionally
