    摘要： A process for the preparation of trimethylsilyl cyanide comprising reacting trimethylsilyl chloride with an approximately equimolar amount of an alkali metal cyanide in the presence of a catalytic amount of a heavy metal cyanide and in the presence of an aprotic solvent with a boiling point above about 150.degree. C., at a temperature between about 130.degree. and 250.degree. C. Advantageously the reaction temperature is between about 160.degree. and 220.degree. C., the alkali metal cyanide is sodium cyanide or potassium cyanide, the heavy metal cyanide is copper(I) cyanide, copper(II) cyanide, zinc cyanide or a complex compound of one of them with an alkali metal cyanide and is employed in about 1 to 8 mol % relative to the alkali metal cyanide, and the mixture of aprotic solvent, heavy metal cyanide and alkali metal chloride remaining in the reaction vessel when the reaction has ended is used directly as the reaction medium for a further batch.

    摘要： The present invention relates to a novel process for preparing known 1-amino-3-phenyluracil derivatives, to novel 1-amino-6-hydroxy-3-phenyldihydro-2,4(1H,3H)pyrimidinedione derivatives of the formula (II) in which R1 is hydrogen, cyano, nitro or halogen, R2 is cyano, nitro, halogen or optionally substituted alkyl or alkoxy, R3 is hydrogen, hydroxyl, mercapto, amino, hydroxyamino, hydrazino, halogen, or one of the radicals —R6, -Q-R6, —NH—R6, —NH—O—R6, —NH—SO2—R6, —N(SO2—R6)2, —CQ1-R6, —CQ1-Q2-R6, —CQ1-NH—R6, -Q2-CQ1-R6, —NH—CQ1-R6, —N(SO2—R6)(CQ1-R6), -Q2-CQ1-Q2-R6, —NH—CQ1-Q2-R6 or -Q2-CQ1-NH—R6, where Q is O, S, SO or SO2, Q1 and Q2 are each independently oxygen or sulphur and R6 is optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl, arylalkyl, heterocyclyl or heterocyclylalkyl, R4 is hydrogen, halogen or optionally substituted alkyl, and R5 is fluorine- and/or chlorine-substituted alkyl, as intermediates for the 1-amino-3-phenyluracil derivatives, and to a process for preparing the intermediates.
