Silylation and alkylation of allenes using chlorosilanes and alkyl halides in the presence of palladium catalyst and Grignard reagents

Allenes react with Grignard reagents and chlorosilanes in the presence of a palladium catalyst giving rise to carbosilylated products bearing carbon groups from Grignard reagents at the central carbon and silyl groups at the terminal carbon. When alkyl halides were used instead of chlorosilanes, the corresponding alkylated products were obtained.

Application of phase-vanishing method with CO gas evolution to carbonylation reactions

Although carbon monoxide (CO) is considered a practical source of the carbonyl functionality in various compounds, handling CO gas is difficult. The phase-vanishing (PV) method, using highly fluorinated solvents as the phase screen, was thus employed, in which CO was evolved for use in organic synthesis. An H-shaped reactor bearing two reaction chambers was employed. In the first chamber, CO was efficiently generated from sulfuric acid and ammonium formate under the PV conditions, and then consumed in the second chamber in a range of palladium-catalysed carbonylation reactions, affording the desired products. Use of this PV system allowed for easy and safe generation of hazardous CO gas, and its use thereof in organic synthesis.

Octaethyldiphosphaferrocene: An efficient ligand in the palladium-catalyzed suzuki cross-coupling reaction

Syntheses of octaethyldiphosphaferrocene 4 and tetraethylphosphaferrocene 5 are presented. Tetraethylzirconacyclopentadiene 1 reacts with PCl3 in dichloromethane to yield the 1-chlorotetraethylphosphole 2, which upon reduction by lithium in excess, yields the teraethylphospholide anion 3. Anion 3 was subsequently converted into 4 or 5 by treatment with FeCl2 or with [Fe(eta6-C9H12)(eta5-C5H5)][PF6] respectively. The structure of diphosphaferrocene 4 was determined. Two conformations are present in the cell: a C2 conformation (alpha = 51.1) in which the P atom of each ring is located above the alpha-carbon atom of the other ring, and a C2h conformation (alpha = 180) in which P atoms point in opposite directions. Reaction of ligand 4 with [Pd(dba)2] yields the bis(octaethyldiphosphaferrocene)palladium(0) complex 6. An X-ray crystallographic study reveals that the overall geometry around palladium is nearly tetrahedral and that both ligands, whose geometry is not significantly perturbed, adopt a bridging mode involving a side-on coordination of the lone pairs. Complex 6 behaves as an efficient catalyst for the coupling reaction between phenylboronic acid and 4-bromoacetophenone in refluxing toluene. A conversion of 98% was obtained with 1¡Á10-4% of catalyst (TON = 9.80¡Á105). The catalytic activity of 6 in coupling reactions between phenylboronic acid and 3-bromothiophene, 2-bromoanisole, and bromobenzene was also investigated.
