Abstract
The present invention generally relates to methods for the synthesis of catalysts, including epoxidation catalysts, and related compounds and catalyst compositions. Embodiments described herein may provide efficient processes for providing catalysts (e.g., epoxidation catalysts) in large quantities and using simplified methods.
Claims32
A method for synthesizing a catalyst, comprising:
- reacting a compound of Formula (I),
- wherein:
- R1 and R2 can be the same or different and each can be hydrogen, alkyl, or aryl, provided that when one of R1 and R2 is hydrogen, the other is alkyl or aryl;
- R3 is a protecting group;
- R4 is a protecting group that can be removed in the presence of an acid;
- and
- R5, R6, R7, and R8 can be the same or different and each can be hydrogen, alkyl, or aryl, to produce a compound of Formula (II),

A composition, comprising:
- a compound having a structure as in Formula (I):
- wherein:
- R1 and R2 can be the same or different and each can be hydrogen, alkyl, or aryl, provided that when one of R1 and R2 is hydrogen, the other is alkyl or aryl;
- R3 is a protecting group;
- R4 is a protecting group that can be removed in the presence of an acid;
- and
- R5, R6, R7, and R8 can be the same or different and each can be hydrogen, alkyl, or aryl.
