Abstract
Los isocianatos de la fórmula (I) , <EMI FILE="99045931_1" ID="1" IMF=JPEG >(I)en la que X e Y están definidos como en la fórmula (I) , se pueden preparar haciendo reaccionar un compuesto de la fórmula (II) o sus sales,<EMI FILE="99045931_2" ID="2" IMF=JPEG >(II)en la que X e Y están definidos como en la fórmuIa (I), con 1 a 6 moles de fosgeno por 1 mol del compuesto de la fórmula (II), en presencia de 2 a 3,5 equivalentes molares de una base por mol del compuesto de la fórmula (II) y en presencia de un disolvente orgá- aprótico a una temperatura de reacción situada en el margen de -30 a + 60°C para formar el compuesto de la fórmula (I).Los compuestos (I) se pueden convertir por reacción con compuestos nucleófilos para formar productos de reacción por adición tales como carbamatos, ureas y sulfonil-ureas, y correspondientes productos, p.ej. sulfonil-ureas herbicidas.
