    摘要: Allophanates of the formula: ##EQU1## wherein: THE X's are oxygen or sulfur;R.sub.1 is hydrogen, certain organic radicals, or halogen; andR.sub.2 and R.sub.3 are certain organic radicals,Are useful for the control of flowering and plant sexual reproduction. A preferred use of the compounds of the present invention is to prevent corn inbreeding by applying the allophanate to the plant at or shortly before tassel emergence.Exempliary of such compounds is: ethyl 4-[1-(4-chlorophenylcarbamoylimino)-1-(methoxy-methyl)]allophanate.

    摘要: The invention relates to a new and advantageous process for the preparation of substituted S-alkyl thiocarbamates having the general formula (I), ##EQU1## wherein R.sup.1 stands for a C.sub.1-4 alkyl group,R.sup.2 stands for a C.sub.1-4 alkyl or cyclohexyl group, orR.sup.1 and R.sup.2 may form together a C.sub.4-6 polymethylene group, andR.sup.3 stands for a C.sub.2-3 alkyl group.In accordance with the invention the substituted O-alkyl thiocarbamates of the general formula (II), ##EQU2## wherein R.sup.1, R.sup.2 and R.sup.3 each have the same meanings as defined above, are subjected to isomerization by heating them at a temperature of 130.degree. to 180.degree.C in the presence of dimethyl sulfate or diethyl sulfate to yield the appropriate S-alkyl esters.
