Abstract
The reaction of NH 2(CH 2) nNH 2 (n = 2 or 3) with C 6F 5Autht (tht = tetrahydrothiopen) or (C 6F 5) mAuCNR (m = 1 or 3; R = Ph or p-tolyl(To)leads to C 6F 5AuNH 2(CH 2) nNH 2 or, respectively, (C 6F 5) mAuC(NHR)[NH(CH 2) nNH 2], which react with (C 6F 4) mAuCNR to give binuclear carbene complexes of the types C 6F 5AuC(NHR)[NH(CH 2) nNH 2]AuC 6F 5, (C 6F 5) mAuC(NHR)[NH(CH 2) nNH](RHN)CAuC 6F 5 or (C 6F 5) 3AuC(NHTo)[NH(CH 2) nNH](ToHN)CAu(C 6F 5) 3. In XAuthe (X = Cl or C 6F 5) or O 3ClOAuPPh 3 the displacement of the tht or OClO 3 group by C 6F 5AuNH 2(CH 2) nNH 2 leads to the binuclear complexes C 6F 5AuNH 2(CH 2) nNH 2AuX or [C 6F 5AuNH 2(CH 2) 2NH 2AuPPh 3]ClO 4. The reaction of cis-[(C 6F 5) 2Au(OEt 2) 2]ClO 4 with diamine renders cis-(C 6F 5) 2AuNH(CH 2) nNH 2]ClO 4 which react with CNPh to give carbene complexes of the type [(C 6F 5) 2 AuNH 2(CH 2) nNHC (NHPh)]ClO 4 and {C 6F 5) 2 AuC(NHPh)[NH(CH 2 nNH] C (NHPh)}ClO 4.
