Description The oxidation reactions and transition metal complexes of cis-bisphenylalkynyl cyclodiphosphazane [cis-(PhCCP)(2)(mu-(NBu)-Bu-t)(2)] (1) is described. The reaction of 1 with aq. H2O2 and elemental selenium afforded bischalcogenides [cis-(PhC CPO)(2)(mu-NtBu)(2)] (3) and [cis-(PhC CPSe)(2)(mu-NtBu)(2)] (4). Treatment of 1 with [Ru(eta(6)-p-cymene)Cl-2](2) and [{Pd(eta(3)-C3H5)Cl}(2)] yielded dinuclear complexes [{Ru(p-cymene)Cl-2}(2){cis-(PhC CP)(2)(mu-(NBu)-Bu-t)(2)11 (5) and [{PdCl(eta(3)-C3H5)}(2){cis-(PhCCP)(2)(mu-(NBu)-Bu-t)(2)}] (6). Mixed ligand complexes [{(2,2'-bPY)CuI}(2){cis-(PhC CP)(2)(mu-(NBu)-Bu-t)(2)}] (7) and [{(1,10-phen)cul}(2)[cis-(PhC CP)(2)(mu-(NBu)-Bu-t)(2)}] (8) were obtained by reacting 1 with CuI followed by the addition of 2,2'-bipyridine and 1,10-phenanthroline, respectively. Treatment of 1 and [trans-(PhCCP)(2)(mu-(NBu)-Bu-t)(2)] (2) with [AuCl(SMe2)] afforded dinuclear complexes [(AuCI)(2)[cis-(PhCCP)(2)(mu-(NBu)-Bu-t)(2)}] (9) and [(AuCl)(2)[trans-(PhC CP)(2)(mu-(NBu)-Bu-t)(2)}] (10), respectively, in good yields. Both the complexes 9 and 10 exhibit intermolecular aurophilic interactions. The Xray analysis showed dimeric structure for 9, whereas 10 consists of a 1D-polymeric structure, due to aurophilic interactions. The crystal structures of 5, 9 and 10 were established by X-ray diffraction analysis. (C) 2015 Elsevier B.V. All rights reserved.
