We consider that molecular collisions and background IR photoradiation enhance the H 2 O 2 decomposition, as mentioned later. of 4,4'-sulfonyldiphenol with SFDPS and FPSF for comparison. The experiment aims to investigate the cis-trans isomerization of Mo(CO) 4 (PPh 3) 2.In order to obtain these compounds, molybdenum hexacarbonyl is first reacted with piperidine (pip), which leads to the formation of cis-Mo(CO) 4 (pip) 2.The ligand exchange with triphenylphosphine at low temperature (40 o C, boiling dichloromethane) affords the cis-Mo(CO) 4 (PPh 3) 2. in all cases. title = "Thermal Decomposition of Bis(triphenylphosphine)(carbonyl)octyliridium(I).
