Claims17
A compound of a heterocyclic selenophosphite having a general structure (I)
- where R2, R3, R4, R5, R6, R7, R8 and R9 are each independently selected from:
- —H, —(C1-C12)-alkyl, —O—(C1-C12)-alkyl, —(C6-C20)-aryl, —O—(C6-C20)-aryl, -halogen, —COO—(C1-C12)-alkyl, —CONH—(C1-C12)-alkyl, —CO—(C6-C20)-aryl, —COOH, —SO3H, —CN, or —[(C1-C12)-alkyl]2, wherein the alkyl and aryl groups are each independently unsubstituted or substituted, wherein the respective substituted —(C1-C12)-alkyl group and substituted —(C6-C20)-aryl group has at least one substituent and the at least one substituent is each independently selected from —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —(C6-C20)-aryl, fluorine, chlorine, cyano, formyl, acyl or alkoxycarbonyl, and
- where —R1 is independently selected from —OH and -Hal, and -Hal is selected from fluorine, chlorine, bromine, or iodine, and wherein optionally the compound of structure (I) is present in a mixture with a rearrangement product of structure (I).
A method for preparing at least one heterocyclic selenophosphite of the general structure (I)
- where R2, R3, R4, R5, R6, R7, R8 and R9 are each independently selected from:
- —H, —(C1-C12)-alkyl, —O—(C1-C12)-alkyl, —(C6-C20)-aryl, —O—(C6-C20)-aryl, -halogen, —COO—(C1-C12)-alkyl, —CONH—(C1-C12)-alkyl, —CO—(C1-C12)-alkyl, —CO—(C6-C20)-aryl, —COOH, —SO3H, —CN, or —N[(C1-C12)-alkyl]2, wherein the alkyl and aryl groups are each independently unsubstituted or substituted, wherein the respective substituted —(C1-C12)-alkyl group and substituted —(C6-C20)-aryl group has at least one substituent and the at least one substituent is each independently selected from —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —(C6-C20)-aryl, fluorine, chlorine, cyano, formyl, acyl or alkoxycarbonyl, and
- where —R1 is independently selected from —OH and -Hal, where -Hal is selected from fluorine, chlorine, bromine, or iodine, optionally in a mixture with a rearrangement product of the compound of the structure (I),
- comprising at least the method step of
- (i) reacting a selenodiaryl of the general structure (II)
- where R2, R3, R4, R5, R6, R7, R8 and R9 in structure (II) are each independently selected from:
- —H, —(C1-C12)-alkyl, —O—(C1-C12)-alkyl, —(C6-C20)-aryl, —O—(C6-C20)-aryl, -halogen, —COO—(C1-C12)-alkyl, —CONH—(C1-C12)-alkyl, —CO—(C1-C12)-alkyl, —CO—(C6-C20)-aryl, —COOH, —SO3H, —CN, or —N[(C1-C12)-alkyl]2, wherein the alkyl and aryl groups are each independently unsubstituted or substituted, wherein the respective substituted —(C1-C12)-alkyl group and substituted —(C6-C20)-aryl group has at least one substituent and the at least one substituent is each independently selected from —(C3-C12)-cycloalkyl, —(C3-C12)-heterocycloalkyl, —(C6-C20)-aryl, fluorine, chlorine, cyano, formyl, acyl or alkoxycarbonyl,
- (ii) with P(Hal)3, where -Hal is selected from fluorine, chlorine, bromine, or iodine,
- (iii) and obtaining at least one heterocyclic selenophosphite of the general structure (I), optionally in a mixture with a rearrangement product of the compound of the structure (I).
