摘要
The photolysis of (eta-5-C5Me5)Re(CO)2Br2 on Si(III) surfaces at 77 K results in cis to trans isomerism. The mechanism of the photoreaction involves CO loss to generate an isomer of (eta-5-C5Me5)Re(CO)Br2 which, upon warming, reacts thermally with CO to generate only trans-(eta-5-C5Me5)Re(CO)2Br2. The first isomer of (eta-5-C5Me5)Re(CO)Br2 is photosensitive and converts to a second isomer which upon reaction with CO yields exclusively cis-(eta-5-C5Me5)Re(CO)2Br2.
