The barrier for rotation about an N-alkylcarbamate C(carbonyl)-N bond is around 16 kcal/mol. In the case of an N-phenylcarbamate, the rotational barrier is lowered to 12.5 kcal/mol, but with N-(2-pyrimidyl)carbamates the barriers are so low (<9 kcal/mol) that the syn and anti rotamers cannot be observed as separate signals by 500 MHz NMR spectroscopy at 183 K. X-ray and computational data show ...
Abstraet--Isopropyl N-phenylcarbamate (propham; IPC) and isopropyl N-(3-chlorophenyl)carbamate (chlorpropham; CIPC) were tested for carcinogenic properties in hamsters and mice. The hamsters were given 0"2 ~ IPC or CIPC in the diet, while mice were given 0' 1 ~ CIPC by the same route, using 0.1% urethane as a positive control. Other mice were given sc injections of CIPC. All experiments include...
The inhibitory effect of nine phenylcarbamates with various substituents was studied. For this purpose, electrochemical sensors were applied under two different conditions: if an enzyme was present in the solution or if the enzyme was immobilized onto the electrode surface. In both cases, 3-[(ethoxycarbonyl)amino]phenyl (4-chlorophenyl)carbamate was found as the most effective inhibitor for but...
