Regioselective activation of CH bonds of naphthyl imines at platinum(II). Crystal structures of [PtMe{1-(2′-ClC6H4CH2NCH)C10H6}PPh3] and [PtMe{2-(2′-ClC6H4CH2NCH)C10H6}PPh3]
摘要:
The reaction of [Pt2Me4(mu-SMe2)(2)] with ligands 1-(Me2NCH2CH2NCH)C10H7 (2a) and 2-(Me2NCH2CH2NCH)C10H7 (2b) carried out in acetone at room temperature produced compounds [PtMe2 {1-(Me2NCH2CH2NCH)C10H7}] (3a) and [PtMe2{1- (Me2NCH2CH2NCH)C10H7}] (3b), respectively, in which the imines act as bidentate [N,N] ligands. cyclometallated [C,N,N'] compounds [PtMe{1-(Me2NCH2CH2NCH)C10H6}] (4a) and [PtMe{2-(Me2NCH2CH2NCH)C10H6}] (4b) were obtained by refluxing toluene solutions of compounds 3a or 3b. Reaction Of [Pt2Me4(mu-SMe2)(2)] with ligands 1-(2'-ClC6H4CH2NCH)C10H7 (2c) and 2-(2'-ClC6H4CH2NCH)C10H7 (2d) produced straightforward metallation to yield [PtMe{1-(2'-ClC6H2CH2NCH)C10H6}SMe2] (5c) and [PtMe{2-(2'-ClC6H4CH2NCH)C10H6}SMe2] (5d) containing a [CN] ligand. Triphenylphosphine derivatives [PtMe{1-(2'-ClC6H4CH2NCH)C10H6} PPh3] (6c) and [PtMe{2-(2'-ClC6H4CH2NCH)C(10)H6}PPh3] (6d) were also prepared. All compounds were characterised by NMR spectroscopics and 6e and 6d were also characterised crystallographically. For both [CN,N'] and [CN] systems, the metallation took place regioselectively at beta-positions of the naphthyl group, (C) 2002 Elsevier Science BN. All rights reserved.
