Abstract:
Tricarbonylrhenium(I)(α-diimine) complexes are of importance because of their strong cytotoxic and fluorescence properties. Syntheses of such complexes were achieved through a two-step process. First, the pentylcarbonato complexes, fac-(CO)3(α-diimine)ReOC(O)OC5H11 were synthesized through a microwave-assisted reaction of Re2(CO)10, α-diimine, 1-pentanol and CO2 in a few hours. Second, the pentylcarbonato complexes are treated with carboxylic, sulfonic and halo acids to obtain the corresponding carboxylato, sulfonato and halido complexes. This is the first example of conversion of Re2(CO)10 into a rhenium carbonyl complex through microwave-assisted reaction.
