alpha-Alkylation of carbonyl compounds by direct addition of alcohols to Enol acetates

A practical alpha-alkylation of ketones and aldehydes has been achieved by the direct addition of alcohols to enol acetates. The moderate Lewis acidity of InI3, CaBr3, and FeBr3 is a key factor in the catalytic cycle, and many different alcohols and enol acetates have been successfully used in this procedure.

PROCESS FOR CO-PRODUCING OLEFINS AND DIESTERS OR DIACIDS STARTING FROM UNSATURATED FATS

In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-diacid or diester) and to recycle the ethylene employed.

The synthesis and structural characterisation of Ru-Sn based derivatives bearing asymmetric X2ClSn- (X = Br and F) anions

Four remarkable ruthenium-tin based derivatives [Ru(eta 5-Cp)(PPh3)2SnF2Cl] (1), [Ru(eta5-Cp)(PPh3)2SnBr2Cl] (2), [Ru(eta5-Cp)(dppe)SnF2Cl] (3) and [Ru(eta 5-Cp)(dppe)SnBr2Cl] (4), Cp = C5H5, were obtained by reacting [Ru(eta5-Cp)(PPh3) 2Cl] or [Ru(eta5-Cp)(dppe)Cl] with SnX2 {X = F or Br}, respectively. They were studied by i.r. NMR (1H, 13C, 31P and 119Sn) and 119Sn-Mo?ssbauer spectroscopies. Additionally, (1) and (4) were structurally authenticated by X-ray crystallography and the results were as follows: (1) orthorhombic, Pbca, V = 15181.7(12) A?3 and Z = 8; (4) monoclinic, P21/n, V = 3503.74(8) A?3 and Z = 4. All compounds exist as formulated only in the solid sate, in solution they re-distribute in a mixture of species such as [Ru(eta5-Cp)(PPh 3)2SnFnCl3-n] and [Ru(eta 5-Cp)(dppe)SnBrnCl3-n] {n = 0, 1, 2, and 3}, as revealed by variable temperature 119Sn NMR experiments.

Synthesis and excited-state propertdies of a novel ruthenium nucleoside: 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine

The synthesis and photophysical properties of a novel ruthenium-modified nucleoside are reported. The key synthetic step to 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine involves the Pd(0)-catalyzed cross-coupling of a propargylamine-derivatized Ru(bpy)32+ and 3?,5?-dibenzoyloxy-2?-deoxy-5-iodouridine. The long-lived 3MLCT excited state (1300 ns) of 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine has an emission maximum centered at 640 nm. Step-scan Fourier transform infrared (S2FTIR) time-resolved spectroscopy reveals the excited-state electron to be localized on the modified bipyridine with the excited-state dipole oriented toward the 2?-deoxyuridine.

Expeditious entry to the chamigrane endoperoxide family of natural products

Several members of the recently reported peroxy chamigrane family of natural products were synthesized via a distereoselective route with a novel facial-selective epoxidation of a spiroundecadiene, a facile epoxide rearrangement, and a Co(II)-mediated silylperoxidation as the key steps. Adaptation of the diastereoselective route to an enantioselective one is also illustrated.

Substituted N and O heterocycles have been synthesized by the cycloisomerization of dienes using a ruthenium-carbene catalyst. The products obtained with and without trimethylsilyl vinyl ether differ (see scheme, Cy = cyclohexyl, Mes = 2,4,6-trimethylphenyl, Ts = p-toluenesulfonyl).

Covalent heterodyads of synthetic chlorophyll derivatives linked with linear rigid substituents at the 20-positions constructing photoexcited energy transfer systems

Chlorophyll and bacteriochlorophyll pigments are important porphyrinoids, which play key roles in light absorption, energy migration/transfer, and electron transfer in natural photosynthesis. Dyads of such pigments have attracted much attention from the viewpoints of mimicking photosynthetic light-harvesting and charge-separating systems. In this study, we report the synthesis and optical properties of heterodyads of zinc chlorin and free-base bacteriochlorin covalently linked by linear rigid substituents at the 20-position, which were prepared from naturally occurring chlorophyll-a. A free-base bacteriochlorin moiety accepted the singlet excitation energy from the zinc chlorin in the heterodyads. In the co-aggregate systems of heterodyads with chlorosomal self-assemblies, the latter transfers the singlet excitation energy to the bacteriochlorin moiety of the former, which are useful for artificial chlorosomal supramolecular light-harvesting systems.

Iridium and ruthenium catalyzed syntheses, hydroborations, and metathesis reactions of alkenyl-decaboranes

The selective syntheses of new classes of 6,9-dialkenyl- and 6-alkenyl-decaboranes and 6-alkyl-9-alkenyl-decaboranes have been achieved via iridium and ruthenium catalyzed decaborane and 6-alkyl-decaborane alkyne-hydroborations. Reactions employing [Cp*IrCl2] 2 and [RuCl2(p-cymene)]2 precatalysts gave beta-E-alkenyl-decaboranes, while the corresponding reactions with [RuI 2(p-cymene)]2 gave the alpha-alkenyl-decaborane isomers, with the differences in product selectivity suggesting quite different mechanistic steps for the catalysts. The alkenyl-decaboranes were easily converted to other useful derivatives, including coupled-cage and functionally substituted compounds, via iridium-catalyzed hydroborations and ruthenium-catalyzed homo and cross olefin-metathesis reactions.
