The transition metal catalysed reactions of benzaldehydes and benzylideneamines with disilanes have been investigated. Palladium phosphine complexes catalyse the double silylation of the C=O bond in benzaldehydes and the C=N bond in benzylideneamines with 1,2-difluoro-1,1,2,2-tetramethyldisilane to yield alpha-(fluorodimethylsilyl)-alpha-(fluorodimethylsiloxy)toluene and N-methyl-N-(fluorodimethylsilyl)-alpha-(fluorodimethylsilyl)benzylamine respectively. When less activated disilanes such as 1,2-dichloro- and 1,2-dimethoxy-1,1,2,2-tetramethyldisilane were employed, the palladium phosphine complexes were less active and selective, resulting in extensive side reactions inclusive of 1,2-disiloxy-1,2-diphenylethane formation. The reaction of benzophenone with the difluorodisilane formed 2,2-dimethyl-4,4,5,5-tetraphenyl- 1,3-dioxa-2-silacyclopentane without affording the corresponding simple double silylation product. The formation of side products such as 1,2-disiloxy-1,2- diphenylethane in the reaction of benzaldehyde and 2,2-dimethyl-4,4,5,5- tetraphenyl-1,3-dioxa-2-silacyclopentane in the reaction of benzophenone appears to suggest intermediacy of radical and silylene species. Tris(dibenzylideneacetone)diplatinum-etpo (etpo = 4-ethyl-1-phospha-2,6,7- trioxabicyclo[2.2.2]octane catalyst system was more active for unactivated disilanes, catalysing double silylation of benzaldehydes with hexamethyldisilane. The same catalyst system was found to catalyse the ortho silylation of benzylideneamines with disilanes via intramolecular C-H activation; both mono- and bis-silylated products were obtained. Reaction rates and product distributions are rationalised in terms of the steric and electronic properties of the disilanes, substrates and the catalyst used. The Royal Society of Chemistry 2003.

Purines bearing phenanthroline or bipyridine ligands and their RuII complexes in position 8 as model compounds for electrochemical DNA labeling – Synthesis, crystal structure, electrochemistry, quantum chemical calculations, cytostatic and antiviral activity

A series of ethynyl- or (4-boronophenyl)bipyridines and -phenanthrolines were prepared as versatile building blocks for attachment of bidentate N-ligands to other molecules via cross-coupling reactions. Their complexation with Ru(bpy)2-Cl2 gave the corresponding RuII complexes. 9-Benzyladenine derivatives bearing the bipyridine or phenanthroline complexes in position 8, attached via a conjugate acetylene or phenylene linker were prepared by cross-coupling reactions of the ethynyl- or 4-boronophenylbipyridines and -phenanthrolines with 9-benzyl-8-bromoadenine. Their complexation with Ru(bpy)2Cl2 afforded the corresponding Ru complexes as model compounds for electrochemical DNA labeling. The same compounds were also prepared directly by cross-coupling of 9-benzyl-8-bromoadenine with Ru complexes of the alkynes and boronic acids. Both approaches are compared in terms of potential applications for labeling of nucleic acids. The crystal structures of two Ru complexes were determined by X-ray diffraction. The electrochemistry of the model purines bearing the phenanthroline or bipyridine ligands and the Ru complexes was studied by means of cyclic or square-wave voltammetry with carbon paste and mercury electrodes. The experimental redox potentials of the title compounds were compared with quantum chemical calculations. A very good agreement between experiment and theory was obtained, with a standard deviation of 0.13 V. It was shown that theoretical calculations can be of a limited predictive power for new Ru II complexes, though it was difficult to reproduce differences smaller than 0.05 V. Several compounds of this series exhibited a considerable cytostatic effect and activity against the hepatitis C virus (HCV). Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Ir-catalyzed borylation of C-H bonds in N-containing heterocycles: Regioselectivity in the synthesis of heteroaryl boronate esters

(Chemical Equation Presented) Blocking the way: Substitution at the 2-position in pyridines and other N-heterocycles blocks N-coordination to an Ir center. This steric hindrance provides a substrate-design criterion that allows the Ir-catalyzed borylation of C-H bonds, which can be followed by Suzuki-Miyaura cross-coupling in a one-pot reaction (see scheme; B 2pin2 = bis(pinacolato-O,O?)diboron, dtbpy = 4,4?-tBu2-2,2?-bipyridine).

Preparation and characterization of Cp-functionalized cycloheptatrienyl- cyclopentadienyl titanium sandwich complexes (troticenes)

Cp-functionalized monotroticenes [(eta7-C7H 7)Ti(eta5-C5H4E)] (2, E = Ph 2SiCl; 3, E = tBu2SnCl; 12, E = I) and bitroticenes [(eta7-C7H7)Ti(eta5-C 5H4)]2E? (5, E? = PPh; 6, E? = BN(SiMe3)2; 7, E? = Cp2Ti) were prepared by salt elimination metathesis between the monolithiated troticene [(eta7-C7H7)Ti(eta5-C 5H4Li)]·pmdta (1b) (pmdta = N,N?,N?, N?,N?-pentamethyldiethylene-triamine) and the appropriate electrophile. The troticenyl-substituted zirconocene monochloride [(eta7-C7H7)Ti(eta5-C 5H4ZrClCp*2)] (Cp* = eta5-C5Me5) (8) and hafnocene ethoxide [(eta7-C7H7)Ti{eta5-C 5H4Hf(OEt)Cp2}] (Cp = eta5-C 5H5) (11), and the heterobimetallic mu-oxo complexes [(eta7-C7H7)Ti(eta5-C 5H4MCp2)]2O (9, M = Zr; 10, M = Hf) were obtained instead of the expected zircona- and hafna[1]troticenophanes by reaction of the dilithiated troticene [(eta7-C7H 6Li)Ti(eta5-C5H4Li)]·pmdta (1a) with [Cp2MCl2] (M = Zr, Hf) or [Cp* 2ZrCl2] in stoichiometric amounts. These compounds were characterized by single crystal X-ray diffraction analyses and, in the case of 2, 3, 5-7, 9, 10 and 12, also by elemental analyses and 1H, 13C and 119Sn NMR spectroscopy. Exposure of the troticenyl organotin chloride 3 to moisture resulted in its partial hydrolysis and formation of the organostannoxane-bridged bitroticene 4, while palladium-catalyzed Negishi C-C cross-coupling reaction between the troticenylzinc chloride [(eta7-C7H7) Ti(eta5-C5H4ZnCl)] (13) and the iodotroticene 12 or iodobenzene (PhI) led to the fulvalene complexes [(eta7- C7H7)Ti(eta5-C5H 4)]2 (14) and [(eta7-C7H 7)Ti(eta5-C5H4Ph)] (15). Compound 4 displays an unsymmetrical structure with the troticenyl fragments cis with respect to the Sn-O-Sn core, whereas compound 14 is centrosymmetrically trans oriented.
