Abstract
Cinnamaldehydeanils reacted readily with [Rh(CO)2Cl]2 under mild conditions to form Rh(CO)2ClL (2), where L is PhCH=CH—CH=NPh or PhCH=CH—CH=NTo (Ph = phenyl, To = p-tolyl). Under vigorous conditions RhCl(CO)L2 (3) was isolated from this reaction. From the infrared and proton magnetic resonance spectra the ligands, L, appear only to coordinate through the nitrogen atom to the rhodium.Cinnamaldehyde reacted with Rh(CO)2Cl(p-toluidine) to give (2b) in good yield. Heating (2) in boiling benzene afforded (3) and Rh metal. Triphenylphosphine reacted with (2) or (3) to form RhCl(CO)(PPh3)2. The reaction of (3) with 1,5-cyclooctadiene gave (1,5-C8H12)RhClL, which was also prepared by reaction of (1,5-C8H12RhCl)2 with L.Some electronegatively substituted acetylenes reacted with (3) to yield the stable acetylene complexes (RC≡CR)RhClL2 (R = CF3, COOMe).Keywords
