The present invention refers to a process for the preparation of a bis(acyl)phosphinic acid silyl ester of the general formula (I), wherein R1, R2, R3, R4, R5, R7, R8, R9, R10 and R11 are the same or different and are independently selected from H, halogen, linear or branched C1-C20-alkyl, linear or branched C2-C8-alkenyl, C1-C8-alkoxy, C2-C8-alkenyloxy, C3-C8-cycloalkyl, C6-C12-aryl, C3-C8-cycloalkoxy, C7-C12-arylalkoxy, C9-C15-alkenylarylalkoxy, nitro-, C6-C12-arylsulfonyl, 4-alkylarylsulfonyl, C1-C20-alkylcarboxy, C1-C8-alkoxycarbonyl, SR12, NHR12 or NR12R13 with R12 and R13 being independently selected from H, linear or branched C1-C20-alkyl, linear or branched C2-C8-alkenyl and C3-C8-cycloalkyl, and an O-, S- or N- containing 5- or 6-membered heterocyclic ring; R6 is OSiR14R15R16 with R14, R15 and R16 being independently selected from linear or branched C1-C20-alkyl or C6-C12-aryl; as well as the bis(acyl)phosphinic acid silyl ester and the bis(acyl)phosphinic acid obtained by the process.
本发明涉及一种制备通式(I)的双(酰基)磷酸硅酯的方法,其中R1、R2、R3、R4、R5、R7、R8、R9、R10和R11相同或不同,可独立地选择自H、卤素、直链或支链的C1-C20-烷基、直链或支链的C2-C8-烯基、C1-C8-烷氧基、C2-C8-烯氧基、C3-C8-环烷基、C6-C12-芳基、C3-C8-环烷氧基、C7-C12-芳基烷氧基、C9-C15-烯基芳基烷氧基、硝基、C6-C12-芳基磺酰基、4-烷基芳基磺酰基、C1-C20-烷基羧基、C1-C8-烷氧羰基、SR12、NHR12或NR12R13,其中R12和R13可独立地选择自H、直链或支链的C1-C20-烷基、直链或支链的C2-C8-烯基和C3-C8-环烷基,以及含有O、S或N的5-或6-成员杂环;R6为OSiR14R15R16,其中R14、R15和R16可独立地选择自直链或支链的C1-C20-烷基或C6-C12-芳基;以及通过该方法获得的双(酰基)磷酸硅酯和双(酰基)磷酸。
