Abstract

Este invento se origina probablemente como intermediario la respectiva 1-hidracinoantraquinona 2-substituida, que reacciona en seguida ulteriormente con cierre del anillo formando la pirazolantrona. Las pirazolantronas 3-substituidas de la fórmula (1) son productos intermediarios importantes para la producción de valiosos colorantes de tina, pigmentos y colorantes de dispersión. Como compuestos de partida de la fórmula (2) cabe citar especialmente: la 1-nitro-2-metilantraquinona, la 1-nitro-2- etilantraguinona y la 1-nitro-2-carboxiantraquinona. Disolventes dipolares apróticos utilizables según este invento son, por ejemplo: la N-metil-2-pirrolidona, la tetrametilurea, el sulfolano, la triamida de ácido hexametilfosfórico, el sulfóxido de dimetilo, la dimetilacetamida, la dietilacetamida, el acetonitrilo, la dimetilformamida, el 3,3'' -tiodipropionitrilo y también la piridina.
