The first photoinduced carbon(sp2)?heteroatom bond forming reaction by a rare-earth-metal photoreductant, a Miyaura borylation, has been achieved. This simple, scalable, and novel borylation method that makes use of the hexachlorocerate(III) anion ([CeIIICl6]3?, derived from CeCl3) has a broad substrate scope and functional-group tolerance and can be conducted at room temperature. Combined with Suzuki?Miyaura cross-coupling, the method is applicable to the synthesis of various biaryl products, including through the use of aryl chloride substrates.

A method for the deprotonative silylation of aromatic C-H bonds has been developed using trifluoromethyltrimethylsilane (CF3SiMe3, Ruppert-Prakash reagent) and a catalytic amount of fluoride. In this reaction, CF3SiMe3 is considered to act as a base and a silicon electrophile. This process is highly tolerant to various functional groups on heteroarenes and benzenes. Furthermore, this method can be applied to the synthesis of trimethylsilyl group-containing analogs of TAC-101, which is a bioactive synthetic retinoid with selective affinity for retinoic acid receptor alpha (RAR-alpha) binding. We also report further transformations of the silylated products into useful derivatives.

An efficient and generally applicable protocol for the palladacycle- catalysed arylation or K2CO3-promoted arylmethylation of diisopropyl H-phosphonate has been developed. The remarkable features of the palladacycle-catalysed arylation reaction include wide substrate scope (aryl iodides, bromides and chlorides), significant shortening of the reaction time (2 or 3 h) and a low catalyst loading of 1 mol-%. Note that with the base K 2CO3 as promoter, arylmethylation could be achieved without any palladium catalyst. Moreover, the first example of a palladium-catalysed phosphonation of inactive electron-rich aryl chlorides with tBuOK as the base has been realized. This result could be considered an important improvement and complement to earlier work of Montchamp and Han, whose catalytic systems are typically compatible with electron-deficient and electron-neutral aryl chlorides.

A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%-85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation-condensation protocol, followed by bromination and Suzuki coupling in the imidazole ring to yield trisubstituted NH-imidazoles (23%-69%, three steps). This approach was also employed in the synthesis of known inhibitor GSK3037619A.

Rate coefficients for detriation of benzothiophen, specifically labelled with tritium at each position, have been measured in anhydrous trifluoroacetic acid, and, for <2-3H>benzothiophen, in a range of trifluoroacetic acid-acetic acid mixtures, all at 70 deg C.The dependence of rate upon acidity is consistent with the effect of hydrogen bonding between sulphur and trifluoroacetic acid, as found previously for other sulphur-containing heterocycles.Partial rate factors, corrected for the effect of hydrogen bonding are (positions in parentheses): 8.84 * 105 (2); 1.18 * 106 (3); 360 (4); 13200 (5); 16200 (6); and 26.2 (7); the corresponding ?+ values are -0.68, -0.695, -0.29, -0.47, -0.48, and -0.16.The positional reactivity order is the same as found in pyrolysis of 1-arylethyl acetates, and solvolysis of 1-arylethyl chlorides, but the ?+ values are more negative due to the greater demand for resonance stabilization of the transition states in hydrogen exchange.Comparison of the 2- : 3-isomer ratios in various substitutions leads to the unexpected conclusion that substitution at the 2-position is subject to steric effects, probably due to the proximity of the sulphur d-orbitals.
