A readily prepared neutral heterobimetallic titanium(IV)-rhodium(I) catalyst for intramolecular hydroacylation.
The combination of HOCMe2CH2PPh2, Ti(OiPr)4, and [Rh(cod)Cl]2 (3:1:1) in either benzene or dichloromethane produces a discrete species (tentatively formulated as complex) that is an active catalyst for intramolecular hydroacylation reactions of 3-substituted pentenals.
