Abstract
Heating a mixture of M2(CO)10 (M = Re, Mn) with 1,2-bis(indenyl)ethane in Decalin at ca. 180 °C provided both monometalated M(CO)3{(η5-C9H6)C2H4C9H7)} (1, M = Re; 3, M = Mn) and bimetalated (M(CO)3)2{μ-(η5-C9H6)C2H4(η5-C9H6)} (2, M = Re; 4, M = Mn) products, which were separated by chromatography, isolated as pure solids, and characterized by a combination of analytical and spectroscopic methods. The bimetalated compounds 2 and 4 were formed as a mixture of meso and rac diastereomers; the rac form of 2 crystallized selectively, and its structure was determined by X-ray crystallography. UV photolysis of 1 and 3 (or 4) yielded the compounds M(CO)2{(η5-C9H6)C2H4(η2-C9H7)} (5, M = Re; 6, M = Mn), in which a carbonyl ligand is replaced by the η2 coordination of the pendant indene group. UV photolysis of 2 gave primarily the rearranged isomer Re2(CO)6{μ-(η1:η2-C9H6)C2H4(η5-C9H6)} (7), in which one indenyl group bridges the two Re centers as an η1:η2-vinyl moiety. The molecular structures of compounds 6 and 7 al...
