    名称:
    Synthesis, spectroscopy, catalysis and crystal structure of [Rh(η4-cod){(R)-N-(Ar)ethyl-2-oxo-1-naphthaldiminato-κ2N,O}] (Ar=C6H5, 3-/4-MeOC6H4, and 4-BrC6H4)
    摘要:
    Condensation of 2-hydroxy-1-naphthaldehyde with (R)-(Ar) ethylamine yields the enantiopure Schiff bases, (R)-N-(Ar)ethyl-2-hydroxy-1-naphthaldimine (Ar = C6H5, 3-/4-MeOC6H4, 4-BrC6H4). These Schiff bases readily react with the dinuclear complex [Rh(eta(4)-cod)(mu-O2CMe)](2) to afford the mononuclear complexes [Rh(eta(4)-cod){(R)-N-(Ar) ethyl-2-oxo-1-naphthaldiminato-kappa N-2,O}] (Ar = C6H5 (I); 3-MeOC6H4 (II); 4-BrC6H4 (III)), respectively in C6H6/MeOH (5:1, v/v). The Schiff bases and complexes are characterized by IR, UV-Vis, H-1/C-13 NMR and mass spectrometry, polarimetry and HPLC. The polarimetric measurements show the enantiopurity of the Schiff bases as well as the complexes. The X-ray structure determination for III demonstrates that the deprotonated Schiff bases, (R)-N-(Ar) ethyl-2-oxo-1-naphthaldiminate, coordinate to the [Rh(eta(4)-cod)]-fragment as a six-membered N,O-chelate ligand with distorted square planar geometry at the rhodium metal atom. Reaction of III with O-2 leads to the formation of the oxidative aduct [Rh(eta(4)-cod)(mu-O)](2) (IIIa). Compound I or [Rh(eta(4)-cod){(S or R)-N-(phenyl) ethyl-salicylaldiminato}] were used for reduction of acetophenone with diphenylsilane into (+/-)-1-phenyl-ethanol, and conversions up to 93-97% have been achieved.
