A practical and direct method was developed for the production of versatile alkyl boronate esters via transition metal-free borylation of primary and secondary alkyl sulfones. The key to the success of the strategy is the use of bis(neopentyl glycolato) diboron (B2neop2), with a stoichiometric amount of base as a promoter. The practicality and industrial potential of this protocol are highlighted by its wide functional group tolerance, the late-stage modification of complex compounds, no need for further transesterification, and operational simplicity. Radical clock, radical trap experiments, and EPR studies were conducted which show that the borylation process involves radical intermediates.

The nitro group of β-nitro sulfides is readily substituted by an allyl or a cyano group or hydrogen on treatment with allyltrimethylsilane, cyanotrimethylsilane, or triethylsilane in the presence of an appropriate Lewis acid.The intramolecular Friedel-Cra

The stereochemistry of the alkyl group transfer reaction between alkylcobaloximes and various sulfur and selenium derivatives has been studied using (1-(2)H1)-1-phenyl-2-propyl(pyridine)cobaloxime of threo configuration.With this complex, the steric course of substitution reactions occuring at the carbon atom bonded to cobalt can be followed conveniently by NMR spectroscopy: this complex reacts with (C6H5S)2, (C6H5Se)2, 2,4-(NO2)2C6H3SCl, C6H5SeCl and CCl3SO2Cl with racemisation.The mechanistic implications of these result are discussed.
