Supramolecular Emulsifiers in Biphasic Catalysis: The Substrate Drives Its Own Transformation

Naturally occurring triglycerides have been hydroformylated through supramolecular means in the presence of cyclodextrins (CDs). During the course of the reaction, a transient supramolecular complex is formed between triglyceride alkyl chains and the appropriate CDs in a well-defined concentration range. The resulting CD/triglyceride supramolecular emulsifiers help convert the triglyceride CC double bonds in biphasic conditions using a water-soluble organometallic catalyst. The catalytic system could be efficiently recycled.
