Photodecomposition of chromium tricarbonyl complexes with styrene, stilbene, and 1,4-diphenylbuta-1,3-diene in solution
摘要:
Photolytic decomposition of styrene, stilbene, and 1,4-diphenylbuta-1,3-diene tricarbonyl chromium complexes in solution results in elimination of the carbonyl ligands and formation of binuclear alkenylarene chromium complexes. The quantum yields and activation and kinetic parameters of these processes were determined, and a scheme was proposed to rationalize photoinitiated transformations of the organochromium compounds under study.

The reaction of mono-Cr(CO)3 complexes of a number of aromatic compounds containing two arene groups with the Mn(CO)3+ transfer agent [(naphthaleneMn(CO)3]+ gave new Cr/Mn diarene heterobimetallic compounds, e.g., (OC)3Cr(η6-C6H5CHCHC6H5-η6)Mn(CO)3+. This and two others of these compounds were characterized by X-ray diffraction. The two metal carbonyl groups were found to be on the same face of the
