A step forward in solvent knitting strategies: Ruthenium and gold phosphine complex polymerization results in effective heterogenized catalysts

Porous polymers based on ruthenium and gold triphenylphosphine complexes (KPhos(Ru), KPhos(Ru)Bi, KPhos(AuCl) and KPhos(AuNTf2)) were prepared via a cost-effective solvent knitting method with [RuHClCO(PPh3)3] or AuXPPh3 (X = Cl, NTf2) as single monomers or combined with biphenyl, which represents a further approach to obtain heterogenized catalysts. The resulting materials mainly preserve the metal coordination environment of their parent complexes, are stable up to 350 °C and have reasonable surface areas (250-300 m2 g-1 for KPhos(Ru)-polymers). KPhos(Ru)s selectively catalyze the imination of alcohols in the presence of base and the results for KPhos(Au)s show they are effective for the intermolecular hydration and hydroamination of alkynes. These materials can be reused several times without significant loss of activity. This novel and simple method affords heterogenized catalysts that combine the reactivity and selectivity of their homogeneous counterparts with the stability and reusability of a heterogeneous framework.

Regiospesific Synthesis of Polysubstituted Phenols via the Palladium-Catalyzed Enyne-Diyne [4 + 2] Cross-Benzannulation Pathway

An efficient method for the synthesis of polysubstituted phenols via the consecutive palladium-catalyzed enyne-diyne [4 + 2] cross-benzannulation reaction and subsequent deprotection step was developed. In all cases, the reactions proceeded in a regiospecific manner affording the corresponding polysubstituted phenols in good overall yields. It was shown that a more useful one-pot methodology could be applied to the synthesis of polysubstituted phenols 4a-e. The synthetically useful p-methoxyphenylacetylene 13 and its monosilylated derivative 12 were smoothly prepared via exhaustive or partial desilylation of bis-silylated aromatic adduct 8c, respectively.

THERMODINAMYCS OF THE ISODESMIC ENOL-TO-METHYL ENOL ETHER EQUILIBRIUM IN WATER

ΔGo values for the isodesmic equilibrium between substituted acetophenone enols and corresponding methyl enol ethers are calculated from previously reported data on equilibrium constants for keto-enol tautomerism and for enol ether formation from ketones.These values agree with those expected from literature data on analogous alcohol-ether isodesmic systems.
