Reactions of N-acetylcysteine adducts of aromatic (di)isocyanates with functional groups of organic molecules [PDF]

, 2008
Glutathione thiocarbamate conjugates of isocyanates play a key role in transport and final reactions of isocyanates in the human body by transcarbamoylation. N-acetylcysteine is the simplest model for thiocarbamate reactions.

New Synthesis Route for PHD Polyols [PDF]

, 2011
The synthesis of polyurea dispersion polyols (PHD) was developed using a new route via depolymerization of polyurethane polyureas by a mixture of at least two glycols in the presence of a consumable catalyst, i. e. a secondary aliphatic amine.

Statistical Methods for the Investigation of Solvolysis Mechanisms Illustrated by the Chlorides of the Carbomethoxy Protecting Groups NVOC and FMOC

Journal of Analytical Methods in Chemistry, 2015
The solvolysis of 4,5-dimethoxy-2-nitrobenzyl chloroformate (NVOC-Cl, 1) is followed at 25.0°C in twenty hydroxylic solvents. A comparison with previously published rates for benzyl chloroformate and p-nitrobenzyl chloroformate indicates that the ...
