Abstract:
The reactions of cluster (μ-H)Os3(CO)10(μ-OH) with ethyl and isopropyl esters ofl-oxyproline were studied. In the presence of Me3NO intermediate complex (μ-H)Os3(CO)9(μ-OH)L (L — isopropyl ester ofl-oxyproline) is formed, which slowly converts to the more stable cluster (μ-H)Os3(CO)9 {μ,η2−−O|CHCH2CH(COOPri)NHC|H2}{μ,η2−−O|CHCH2CH(COOPri)NH¯C|H2} . Cluster complexes containing chelate-bridging heterocycles were also obtained by heating (μ-H)Os3(CO)10(μ-OH) with esters ofl-oxyproline. In both cases, only one of the possible diastereomeric complexes (μ-H)Os3(CO)9 {μ,η2−−O|CHCH2CH(COOPri)NHC|H2}{μ,η2−−O|CHCH2CH(COOPri)NH¯C|H2} (R = Et, Pri) is formed, which indicates that the reactions are stereospecific. Based on analysis of Dreiding's models, an attempt to determine the absolute configuration of the obtained clusters was made.
