A highly regioselective ruthenium-catalyzed ortho-arylation of substituted N-alkyl benzamides with aromatic boronic acids in the presence of [{RuCl(2)(p-cymene)}(2)], AgSbF(6), and Ag(2)O is described. Further, ortho-arylated N-alkyl benzamides were converted into fluorenones in the presence of trifluoroacetic anhydride and HCl.

The synthesis and characterization of cationic ruthenium(II) complexes of the type [Ru(η(6)-p-cym)Cl{Ph(2)P(CH(2))(n)S(O)(x)Ph-κP,κS}][PF(6)] (n = 1-3; x = 0, 1; p-cym = p-cymene) are presented. Furthermore, their high biological potential even against cisplatin-resistant tumor cell lines and their structure-activity relationships are discussed.

Substituted acetanilides reacted with aromatic acids in the presence of [{RuCl2(p-cymene)}2], AgSbF6 and (NH4)2S2O8 in ClCH2CH2Cl at 100 °C for 24 h yielding ortho-benzoxylated acetanilides in good to excellent yields in a highly regioselective manner via C-H bond activation.

[Ru(p-cymene)Cl2]2-catalyzed 1,4-addition reactions between arylboronic acids and butyl acrylate and acrylamide in the presence of phenols were investigated, good to excellent yields were obtained. The addition of phenols remarkably promoted the protonolysis and inhibited the β-H elimination of the 1,4-addition intermediates, and also efficiently suppressed the protonolysis of arylboronic acids.

Thymus hyemalis L. and Spanish Thymus vulgaris L. shrubs are characterized by a large chemical intraspecific variability among he plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. ased on this, the clones of T. hyemalis and Spanish T. vulgaris were used in this present work to monitor seasonal variations in the ...

Recyclable ( -p-cymene)-ruthenium(II) 2-naphthylazo-p-methylphenolate catalyst of formulation [RuCl( -pcymene)(L)] (where L = mono anionic 2-naphthylazo-p-methylphenolate ligand) is shown to be an efficient catalyst for transfer hydrogenation of a wide range of alkyl and aryl ketones in the presence of 2-propanol and KOH.

The waterdistilled essential oil from dried aerial parts of one of the Algerian thymes, Thymus fontanesii Boiss. & Reut. grown in Setif province, Algeria, was analyzed by GC/MS. Fifteen components were characterized representing 99.4% of the total components detected. The major components of the oil were thymol (67.8%), gamma-terpinene (15.9%) and p-cymene (13.0%).

The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

The highly porous and robust [Ni(8)(OH)(4)(OH(2))(2)(4,4'-(buta-1,3-diyne-1,4-diyl)bispyrazolato)(6)](n) MOF can be used as a proof of concept for the incorporation and release of the non-conventional [Ru(p-cymene)Cl(2)(pta)] RAPTA-C metallodrug.
