Abstract

Complete assignments of FTIR and Raman spectra are proposed for Ni(CO 2 )(PCy 3 ) 2 and its 13 CO 2 - and C 18 O 2 -labeled derivatives. Normal coordinate analysis gives a relevant force-field for side-on complexation at the solid state and shows that the complex can also exist with an «end-on» coordination mode. FTIR study in various solvents at different temperatures allows us to conclude that similar coordination modes are found in solution. Results are compared to that obtained by 13 C and 31 P NMR (including CPMAS studies) concerning the fluxionality of Ni-(CO 2 )(PCy 3 ) 2

4. Mechanism of Formation of Peroxocarbonates RhOOC(O)O(Cl)(P)(3) and Their Reactivity as Oxygen Transfer Agents Mimicking Monooxygenases. The First Evidence of CO(2) Insertion into the O-O Bond of Rh(eta(2)-O(2)) Complexes

Abstract

Extended labeling experiments have shown that formation of rhodium peroxocarbonate from CO(2) and [RhCl(eta(2)-O(2))(P)(3)] (P is PEt(2)Ph or PEtPh(2)) proceeds through O-O bond cleavage and CO(2) insertion. O-transfer to ancillary phosphine ligand to give R(3)P=O selectively (85%) involves the Rh-linked O atom of the peroxo group of RhCl(CO(4))(P)(3).
