Abstract
Изобретение относится к способам получения одно- или более замещенных или незамещенных гидроксиальдегидов, например 6-гидроксигексаналей, который включает введение одно- или более замещенных или незамещенных алкадиенов, например бутадиена, в реакцию восстановительного гидроформилирования в присутствии катализатора восстановительного гидроформилирования, например комплекса металла с фосфорорганическим лигандом, и реакцию гидроформилирования в присутствии катализатора гидроформилирования, например комплекса металла с фосфорорганическим лигандом, для получения одно- или более замещенных или незамещенных гидроксиальдегидов. Замещенные и незамещенные гидроксиальдегиды, получаемые заявленным способом, подвергают дополнительной реакции (реакциям) для получения их желаемых производных, например эпсилонкапролактона. Это изобретение также частично относится к реакционным смесям, включающим одно- или более замещенные или незамещенные гидроксиальдегиды в качестве основного продукта (продуктов) реакции.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to methods for producing one or more substituted or unsubstituted hydroxyaldehydes, for example 6-hydroxyhexanals, which involves the introduction of one or more substituted or unsubstituted alkadiens, for example butadiene, in the reaction of reductive hydroformylation in the presence of a catalyst for reductive hydroformylation, for example, a complex of an organophosphate ligand , and the reaction of hydroformylation in the presence of a catalyst of hydroformylation, for example, a complex of a metal with phosphorus nical ligand to produce one or more substituted or unsubstituted hydroxyaldehydes. The substituted and unsubstituted hydroxyaldehydes obtained by the claimed method undergo an additional reaction (reactions) to obtain their desired derivatives, for example, epsilon caprolactone. This invention also relates in part to reaction mixtures comprising one or more substituted or unsubstituted hydroxyaldehydes as the main product (s) of the reaction. The international application was published along with an international search report.
