The first metal-free and facile radical addition/cyclization of simple alcohols with diaryl(arylethynyl)phosphine oxides has been described with azobisisobutyronitrile as a radical initiator, affording an efficient and one-pot procedure to access a new cl

An array of coordination-driven supramolecular metal-ligand clusters has been synthesized using polytopic phosphine ligands and coinage metals (Cu +, Ag+, Au+). Rigid 3-fold or 2-fold symmetric phosphine ligands have been prepared: 1,3,5-tris((4-(diphenylphosphino)ethynyl) phenyl)benzene) (tppepb, L1), 1,4-bis((diphenylphosphino)ethynyl) benzene (1,4-dppeb, L2), 1,3-bis((diphenylphosphino)ethynyl)benzene (1,3-dppeb, L3), 2,6-bis((diphenylphosphino)ethynyl)pyridine (2,6-dppep, L4), and 1,5-bis((diphenylphosphino)ethynyl)naphthalene (1,5-dppen, L5). Self-assembly of these ligands with coinage metals produces four different types of metal-ligand clusters, or in some cases coordination polymers, depending on number and relative geometry of the phosphine donor atoms. Supramolecular tetrahedral clusters of the formula M 4(L1)4I4 (M = Cu+, Ag+, Au+) were obtained with the tppepb ligand, encapsulating solvent molecules (either CH2Cl2 or DMF) as guests within the central cavity of the clusters. The ligands 1,3-dppeb (L 3) and 2,6-dppep (L4) give achiral, triple-stranded, dinuclear mesocates with the formula M2(L)3I2 (M = Cu+ or Au+). In contrast, the ligand 1,4-dppeb (L2) generates a triple-stranded, dinuclear helicate with Cu +, but a coordination polymer with Au+ (both with the empirical formula M2(L2)3I2). Finally, coordination polymers were obtained from 1,5-dppen (L5) with Cu+. The clusters have been fully characterized by single crystal X-ray crystallography, high-resolution mass spectrometry, 1H NMR, and 31P NMR.

The reaction of [CpRuCl-(PPh3)2] (Cp= cyclopentadienyl) and [CpRuCl(dppe)] (dppe=Ph2PCH2CH 2PPh2) with bis-and trisphosphine ligands 1,4-(Ph 2PC= C)2C6H4 (1) and 1,3,5-(Ph 2PC= C)3C6H3 (2), prepared by Ni-catalysed cross-coupling reactions between terminal alkynes and diphenylchlorophosphine, has been investigated. Using metal-directed self-assembly methodologies, two linear bimetallic complexes,[{CpRuCl(PPh 3)}2(μ-dppab)] (3) and[{CpRu(dppe)}2(μ- dppab)](PF6)2 (4), and the mononuclear complex [CpRuCl(PPh3)(η1-dppab)] (6), which contains a dangling arm ligand, were prepared (dppab=1,4-bis[(diphenylphosphino) ethynyl]benzene). Moreover, by using the triphosphine 1,3,5- tris[(diphenylphosphino)ethynyl]benzene (tppab), the trimetallic [{CpRuCl-(PPh3)}3(μ3-tppab)] (5) species was synthesised, which is the first example of a chiral-at-ruthenium complex containing three different stereogenic centres. Besides these open-chain complexes, the neutral cyclic species [{CpRuCl(μdppab)}2] (7) was also obtained under different experimental conditions. The coordination chemistry of such systems towards supramolecular assemblies was tested by reaction of the bimetallic precursor 3 with additional equivalents of ligand 2. Two rigid macrocycles based on cis coordination of dppab to [CpRu-(PPh 3)] were obtained, that is, the dinuclear complex [{CpRu(PPh 3)(mdppab)}2](PF6)2 (8) and the tetranuclear square [{CpRu(PPh3)(mdppab)}3](PF 3)3 (9). The solid-state structures of 7 and 8 have been determined by X-ray diffraction analysis and show a different arrangement of the two parallel dppab ligands. All compounds were characterised by various methods including ESIMS, electrochemistry and by X-band ESR spectroscopy in the case of the electrogenerated paramagnetic species.
