摘要： The invention relates to adducts that can be obtained by reacting carbonyl compounds of general formula (I) in which the variables are defined as follows: R1 and R2 are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby R1 and R2 can be bound to one another while forming a ring. These carbonyl compounds are reacted with cyclic compounds of general formula (II) in which the variables are defined as follows: X is selected among oxygen, sulfur and N-R8; R3 and R8 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, formyl, CO-C1-C12 alkyl, CO-C3-C12 cycloalkyl, substituted or unsubstituted, CO-C7-C13 aralkyl, CO-C6-C14 aryl, whereby in the event X = N-R8, R3 and R8 can be bound to one another while forming a ring; R4, R5 and R6 are the same or different and are selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals at time can be bound to one another while forming a ring; n represents a integer ranging from 1 to 4, and; R7 is the same or different and is selected among hydrogen, C1-C12 alkyl, C3-C12 cycloalkyl, substituted or unsubstituted, C7-C13 aralkyl, C6-C14 aryl, substituted or unsubstituted, whereby two adjacent radicals R7 at time can be bound to one another or R6 or R4 can be bound to adjacent R7 while forming a ring.
