| Description
| - Studies were made of the kinetics of methoxide ion-catalysed reactions of seven substituted phenyl N-(2-thiocarbamoylphenyl)carbamates, 4-methoxyphenyl N-(2-thiocarbamoylphenyl)-N-(methyl)carbamate and five substituted phenyl N-(4-thiocarbamoylphenyl)carbamates, leading to the respective cyclisation products (i.e. 4-thioxo-1H,3H-quinazolin-2-one or 1-methyl-4-thioxo-1H,3H-quinazolin-2-one) and/or methanolysis product, i.e. methyl N-(4-thiocarbamoylphenyl)carbamate. It was found that the ring closure reaction proceeds by the BAc2 mechanism with the splitting off of phenoxide anion being the rate-limiting step, while the methanolysis follows the E1cB mechanism. The ring closure reaction of 4-methoxyphenyl N-(2-thiocarbamoyl)-N-(methyl)carbamate proceeds kinetically in two steps.

- Byla studována kinetika reakce sedmi substitutovaných fenyl N-(2-thiokarbamoylfenyl)karbamátů, 4-methoxyfenyl N-(2-thiokarbamoylfenyl)-N-(methyl)karbamátu a pěti substituovaných fenyl N-(4-thiokarbamoylfenyl)karbamátů s metahnolátem sodným poskytující odpovídající produkty cyklizace (tj. 4-thioxo-1H,3H-chinazolin-2-on nebo 1-methyl-4-thioxo-1H,3H-chinazolin-2-on) a methanolýzy , tj. methyl N-(4-thiokarbamoylfenyl)karbamát. Bylo zjištěno, že cyklizace probíhá BAc2 mechanismem s rychlost určujícím odštěpováním fenolátového aniontu , kdežto methanolýza probíhá E1cB mechanismem. Cyklizace 4-methoxyfenyl N-(2-thiokarbamoyl)-N-(methyl)karbamátu probíhá kineticky ve dvou krocích. (cs)
