Ring-opening hydroformylation of α-cyclopropylstyrene by HMn(CO)5, and structure of a novel Mn2(CO)9(η1-aldehyde) complex
Abstract
An η1-aldehyde complex, Mn2(CO)9[Me(Ph)CCHCH2CH2CHO], was isolated from the reaction of α-cyclopropylstyrene with wet HMn(CO)5; the crystal structure of this unusual compound confirmed the η1(σ) bonding of the aldehyde oxygen as an equatorial ligand on Mn2(CO)9.
