Anti-Markovnikov stereoselective addition of bis(trimethylsilyl)octadiene to ketal obtained by unprecedented retro-Claisen condensation of 3-hydroxy-2,4-pentanedione bis-ketal

In the course of the Lewis acid-mediated cycloaddition of 1,8-bis(trimethylsilyl)-2,6-octadiene to bis-ketals, we have observed an unprecedented retro-Claisen condensation from the ketalisation of a 3-hydroxy-2,4-pentadione giving rise to a substituted 2,

Rh(I) complexes bearing N, N and N,P ligands anchored on glassy carbon electrodes: Toward recyclable hydroamination catalysts

A series of N,N-donor ligands (bis(pyrazol-1-yl)methane (bpm), bis(N-methylimidazol-2-yl)methane (bim), 1-(phenylmethyl)-4-(1H-pyrazol-1-yl methyl)-1H-1,2,3-triazole (PyT)), and one N,P-donor ligand precursor (1-(3,5-dimethylpyrazol-1-yl)(2-bromoethane) (dmPyBr)) were synthesized and functionalized with aniline. Diazotization of the aniline into an aryl diazonium, using nitrous acid in aqueous conditions, was performed in situ such that the ligands could be reductively adsorbed onto glassy carbon electrode surfaces. The N,N-donor ligands (bpm, bim, PyT) were immobilized in a single step, while several steps were required to immobilize the N,P-donor ligand (dmPyP) to prevent oxidation of the phosphine group. The complexation of the anchored ligands with the metal complex precursor ([Rh(CO)2(μ-Cl)] 2) led to the formation of anchored Rh(I) complexes with each of the ligands (bpm, bim, PyT, dmPyP). X-ray photoelectron spectroscopy (XPS) confirmed the formation of the anchored ligands as well as the anchored complexes. The surface coverage of functionalized electrodes was estimated by means of cyclic voltammetry, and the nature of the coverage was close to being a monolayer for each immobilized complex. The anchored Rh(I) complexes were active as catalysts for the intramolecular hydroamination of 4-pentyn-1-amine to form 2-methyl-1-pyrroline.
