  η¹-Ligation versus Pnictogen−Carbon Double Bond Cleavage:  The Contrasting Behavior of Phospha- and Arsaalkenes [Tp*(CO)₂M⋮C−EC(NMe₂)₂] [E = P, As; M = Mo, W; Tp* = HB(3,5-Me₂pz)₃] toward [Au(CO)Cl]

  摘要：

  Reaction of [Tp*(CO)(2)M=C-P=C(NMe2)(2)] [1a, M = Mo; Ib, W; Tp*=HB(3,5-Me(2)pz)(3)] with 2 molar equiv of [Au(CO)Cl] afforded the trinuclear complexes [Tp*(CO)(2)M=C-P(AuCl)(2)C(NMe2)(2)] 2a (M = Mo) and 2b (M = W). In marked contrast to this the arsenic analogues [Tp*(CO)(2)M=C-As=C(NMe2)(2)] (3a, M = Mo; 3b, M = W), when treated with the gold complex, give rise to As=C cleavage with formation of the gold carbene complex [ClAuC(NMe2)(2)] (5) and the functionalized cyclotriarsanes [{Tp*(CO)(2)M=C-As}(3)] 4a (M = Mo) and 4b (M = Mo). Compounds 2a,b and 4a,b have been characterized by IR and H-1 and C-13 NMR spectroscopy. In addition, the molecular structures of 2a, 2b, and 5 have been determined by single-crystal X-ray structural analyses.

  mu-(1,2-Diisocyanobenzene)bis(chlorogold) (2) reacts with 1,2-diaminobenzene (1/1) to give benzimidazolin-2-ylidene(chloro)gold (3) as the only reaction product, while 1/1-mixtures of 3 and the corresponding diaminocarbene complexes (4, 6) result from the reactions of 2 with 1,8-diaminonaphthalene or two equivalents of aniline. With one equivalent of a primary amine (MeNH2, PhNH2), however, the isocyanide complexes Au(Cl)CNR (R = Me, Ph) are obtained, again together with 3. Mechanistic key steps following the primary nucleophilic attack by the amine are a novel NC-coupling of the two neighbouring isocyano functions to give a benzimidazole ring system, and the transfer of the exocyclic Au(Cl)C fragment onto the incoming amine. Accordingly, the reactions between 2 and secondary amines lead to an isolable binuclear intermediate C' (1/1) or to the carbene complexes Au(Cl)C(NR2)2} (8, 2R = (CH2)5; 9, 2R = (CH2)2O(CH2)2; 10, R = Me; 11, 2R = (CH2)4) (1/2), respectively.7 and morpholine give 3 and the asymmetrical diaminocarbene complex Au(Cl)C[ activated N(CH2)4CH2]-[ activated N(CH2)2OCH2CH2]} (12).
