Palladium-assisted rearrangement of HC(O)C6H2(OMe)3-3,4,5 to HC(O)C6H2(OMe)3-2,3,4. X-Ray structures of [PdR(PPh3)(bipy)](CF3SO3)[R = C6H(CHO)-6,(OMe)3-2,3,4 and C6H(CHO)-2,(OMe)3-3,4,5; bipy = 2,2′-bipyridyl]

Abstract

The anionic complex [Pd₂R₂Cl₂(µ-Cl)₂]^2–{1, R = C₆H(CHO)-6,(OMe)_3^– 2,3,4} and the neutral [Pd₂R′₂(µ-Cl)₂]{2, R′= C₆H(CHO)-2,(OMe)₃-3,4,5} are both obtained by reaction of HgR₂ with appropriate palladium precursors; the isomerization of R to R′ was confirmed by X-ray studies of the derivatives [PdR(PPh₃)(bipy)](CF₃SO₃)5 and [PdR′(PPh₃)(bipy)](CF₃SO₃)5′.
