| Popis: | A survey is made of the reactions of chelating ketones and aldehydes with [(CO) 2 RhCl] 2 . With the enolizable ketone 8-quinolinyl benzyl ketone a rhodium(I)-vinyl alcohol π-complex forms, whose crystal structure was determined (C 18 H 13 NO 2 ClRh, monoclinic space group C 2/ c , a 14.531(3), b 18.038(3), c 15.257(3) A, β 111.48(1)°, V 3721 A 3 , Z = 8, final R w 4.16%). The non-enolizable ketone 8-quinolinyl phenyl ketone gives oxygen atom transfer to CO, producing CO 2 and a 1,3-dirhodiametallacyclobutane complex. Oxygen atom transfer is also seen from 8-nitroquinoline to give a chelating nitroso ligand. Finally 8-quinoline carboxaldehyde undergoes CH activation followed by loss of H 2 to give a dimeric acylrhodium(II), whose crystal structure was determined (C 26 H 12 N 2 O 8 Cl 4 Rh 4 , orthorhombic space group Pccn , a 9.466(5), b 13.648(9), c 24.124(14) A, V 3119 A 3 , Z = 4 final R w 5.68%). |
