Abstract
Process for obtaining esters of carbaminic acid of formula I ** (See formula) ** wherein each of the radicals Ar1 and Ar2 signify an aryl radical or a heterocyclic radical with aromatic character, each of the radicals R1 and R2 means an aliphatic radical or, taken together, a divalent aliphatic radical, each of the R4 groups and R5 means a hydrogen atom, a lower alkyl radical, a halogen atom or the radical of formula Ia ** (See formula) ** one of the radicals X1 and X2 means one sulfur atom or one oxygen atom and the other one a sulfur atom and R5 a hydrogen atom, an aliphatic radical or an araliphatic radical, characterized in that a) in a compound of formula IV ** (See formula) ** where Rº means a transformable substituent on the radical of formula Ia and each of the radicals Rº 3 and Rº 4 means a hydrogen atom, a lower alkyl radical, a halogen atom or the radical Rº, or in a salt thereof , an R substituent is transformed into the radical of formula Ia, or b) in a compound of formula V ** (See formula) ** where R 'means a transformable substituent on the radical of formula Va ** (See formula) ** it is transformed into the radical Va, and if desired, into a compound obtained, in which X 2 signifies an oxygen atom, the latter being replaced by a sulfur atom and/or, if desired, in a compound obtained in wherein R5 signifies a hydrogen atom, the latter being replaced by an aliphatic radical or an araliphatic radical and/or, if desired, a compound obtained where X1 signifies an oxygen atom and X2 is a sulfur atom, isomerized to a compound in which X 1 means a sulfur atom and X 2 an oxygen atom.
