Ring-opening Hydroformylation of α-Cyclopropylstyrene by HMn(CO)5, and Structure of a Novel Mn2(CO)9(η1-Aldehyde) Complex

Article abstract of DOI:10.1039/c39890000261

An η¹-aldehyde complex, Mn2(CO)9, was isolated from the reaction of α-cyclopropylstyrene with wet HMn(CO)5; the crystal structure of this unusual compound confirmed the η¹ (?) bonding of the aldehyde oxygen as an equatorial ligand on Mn2(CO)9.
