Transition metal complex compound having half sandwich structure and donor-acceptor groups

摘要

A transition metal complex compound having a half sandwich structure and donor-acceptor groups is claimed. A pi -complex compound of a transition metal (I) is of formula (1) and/or (2): -(Spacer)0,1(P<+>(R<1>R<2>)-C(R<3>R<4>))<+>-(Spacer)0,1- (3); -(Spacer)0,1(P(R<1>R<2>)...-C(R<3>))-(Spacer)0,1- (4); -(Spacer)0,1(P<+>(R<1>R<2>)-N(R<3>R<4>))<+>-(Spacer)0,1- (5); -(Spacer)0,1(P(R<1>R<2>)...-N(R<3>))-(Spacer)0,1- (6); -(Spacer)0,1(P(R<1>R<2>)...-N-)-(Spacer)0,1- (7); -(Spacer)0,1S<+>(R<1>)-C(R<3>R<4>)-(Spacer)0,1- (8); -(Spacer)0,1S(R<1>)...-C(R<3>)-(Spacer)0,1- (9); -(Spacer)0,1S(=O)-C(R<3>R<4>)-(Spacer)0,1- (10); -(Spacer)0,1S(=O)...-C(R<3>)-(Spacer)0,1- (11); -(Spacer)0,1S(=O)2-C(R<3>R<4>)-(Spacer)0,1- (12); pi = a charged or neutral pi -system, optionally of mono or di-condensed saturated 5-6 membered rings and where H atoms in the condensed or non-condensed form are optionally partially or fully substituted by 1-20 C (cyclo)alkyl, 1-20 C halo(cyclo)alkyl, 2-20 C (cyclo)alkenyl, 1-20 C (cyclo)alkoxy, 7-15 C aralkyl, 6-12 C aryl or once or twice through D or A; D = donor atom; A = acceptor atom. D and/or A are bonded to M directly or through a spacer whereby D and A are bonded via a coordinative bond and D has a positive (partial) charge) and A has a negative (partial) charge; M = a Group III-VIII , preferably III-VI element, lanthanide or actinide; X = anion equivalent; n = 0-4. D is bonded via a spacer or directly to pi bonded disubstituted N, P, As, Sb or Bi or mono substituted O, S, Se or Te and A is bonded via a spacer or directly to M (B, Al, Ga or In) or D and A are bonded via a spacer or directly to pi and/or M via formulae (3)-(7), phosphonium salt, phosphorylide, aminophosphonium salt or phosphinimine or the corresponding ammonium salt and nitrogen ylid, arsonium salt or arsenylide, sulfonium salt or sulfur ylid, selenium salt or selenylide, the corresponding aminoarsonium salt or arsinimine, aminosulfonium salt or sulfinimine, aminoselenium salt or selenimine, formula (8)-(12) and the corresponding sulfimine structures. R<1>-R<4> = 1-20 C (cyclo)alkyl, 1-20 C halo(cyclo)alkyl, 2-20 C (cyclo)alkenyl, 1-20 C (cyclo)alkoxy, 7-15 C aralkyl, 6-12 C aryl, 7-15 C aralkoxy, 6-12 C aryloxy, indenyl, halogen, 1-thienyl, disubstituted amine, trisubstituted silyl, optionally bonded via -CH2- or phenyl-acetylenyl; spacer = divalent silyl, germanyl, amino, phosphino, methylene, ethylene, propylene, disilylethylene or disiloxane, optionally substituted with up to four 1-4 C alkyl, phenyl or 4-6 C cycloalkyl and is bonded directly to pi by P, N, As, S and/or Se.
