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, -(CO)(α-diimine)ReOC(O)OCH were synthesized through a microwave-assisted reaction of Re(CO), α-diimine, 1-pentanol and CO 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 Re(CO) into a rhenium carbonyl complex through microwave-assisted reaction.
三羰基铼（I）（α-二亚胺）配合物因其强大的细胞毒性和荧光特性而备受关注。此类配合物通过两步法合成。首先，通过在数小时内将铼（CO）、α-二亚胺、1-戊醇和一氧化碳进行微波辅助反应，合成戊基碳酸酯配合物-（CO）（α-二亚胺）ReOC（O）OCH。其次，将戊基碳酸酯配合物用羧酸、磺酸和卤代酸处理，以获得相应的羧基、磺基和卤化物配合物。这是通过微波辅助反应将铼（CO）转化为铼羰基配合物的首个实例。
