научный текст переводится в формате: (DE) Gegenstand der Erfindung ist die Verwendung von Diketo-Verbindungen der Formel (I), in der X einen gesättigten oder ungesättigten Alkylenrest mit 2 bis 4 C-Atomen darstellt, der gegebenenfalls durch Halogen-, Hydroxy-, C1-C4-Alkoxy-, C1-C4-Alkyl-, C1-C4-Hydroxyalkyl-, C1-C4-Alkoxy-(C1-C4)-ALKYLSUBSTITUERVCHKLIK Tillie-Ger best SSPSSSPSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSThis means that under certain conditions, the alkylen rest X in the diketo-Verbindungen (compounds) can undergo self-condensation, forming a cyclic structure, especially a cycloaliphatic ring. This ring can have different sizes depending on the number of reacting units. For example, in the case of v.flush(x) as the reacting unit, a six-membered ring will be formed. The above statement can also be expressed as: cyclo condensation reactions are possible with the reacting unit X, which compete for reaction with itself, leading to a cyclic compound of variable size. Such cyclocondensation reactions are typically conducted at high temperatures. For the reaction to proceed favorably, the substitution pattern of X must satisfy certain requirements. The ring sizes are restricted, for example, for v.flush(x), the ring will have six atoms, and allowing X having two reacting sites creates an intra ring formation. formation reaction is also possible if X has at least two identical and adjacent reactive groups. Thus, X with two identical reactive groups to which one of the groups is the active site, and substituting with another group creates a intra molecule formation. The substitution pattern of X can be controlled by the specific choice of reactive groups attached to X.
In this regard, substituents on the two ends of the alkylen rest X can be modified, where if X is used alone, the arrangement would favor a 6-membered ring in most cases. Different substituent combinations can lead to different ring sizes. For example, if X has only one reactive group, then only a 5-membered ring would be formed when used in a cyclocondensation reaction. These substituent effects must be fully considered when optimizing the reaction conditions and process parameters for the formation of rings of specific ring sizes. Additionally, a certain degree of control over the ring distribution in the reaction and process can be achieved by varying the substituent choice. Depending on the energies of the rear reactive sites in X, different ring sizes can be obtained. For example, if the reactive positions are front of X, then a five-membered ring can be formed instead of the latter. Thus, with careful selection of the specific reactive group substituents for X, it is possible to acquire various ring sizes, including five, six, or seven member rings, depending on the
formation type and additive content. Additionally, cyclic structures can be formed via conjugate addition reactions. Here, though, X needs to have at least one carbonyl group (C=O) as the active site, and upon addition, the carbonyl group will become an ether or carbonyl group of some sort. reforms can also lead to a six-membered ring as in the former cyclo condensation case.
