Twofold unsymmetrical C-Si bond bifunctionalization of 2,6-di(trimethylsilyl) benzyl alcohols has been achieved in one pot via sequential [1,4]-Csp2 to O-silyl migration. The hydroxyl group functions as an "on-off-on" switch to control two successive silyl migrations, and 4,7-dimethyl-o-phenanthroline ligand favors cleavage of the endocyclic C-Si bond. Diverse Csp3/Csp3 or Csp2/Csp3 electrophiles can be installed at the 2- and 6-positions. This approach was used to chemoselectively functionalize the three C-Si bonds of 2,4,6-tri(trimethylsilyl) benzyl alcohol, transforming it into isochroman derivatives. The approach even works as a five-component reaction to construct complex symmetric structures.

A mild and convenient method for the synthesis of a new optically active bis(6,6-dimethylbicyclo[3.1.1]hept-2-en-2-ylmethyl)selenide 1 from the corresponding bicyclic terpene is described. The structure of the obtained organoselenium compound was establis
Halofluorination of alkenes using trihaloisocyanuric acids and HF-pyridine

Halofluorination of alkenes with a new system (trihaloisocyanuric acids and HF-pyridine) results in the formation of vicinal halofluoroalkanes. The reaction is regioselective leading to Markovnikov-oriented products and the halofluorinated adducts follow anti-addition in the case of cyclohexene and 1-methylcyclohexene. Reaction yields range from 67-88%. Georg Thieme Verlag Stuttgart · New York.
