It has been established that the demethylation of bis(trimethylsilyl)alkanes of the general formula Me3SiRSiMe3 by concentrated sulfuric acid, followed by fluorination with ammonium hydrogenfluoride, can successfully be used for the method generally applicable to the preparation of bis(fluorodimethylsilyl...

After an initial section on the direct conversion of organic halides to organomercurials, a variety of transmetallation reactions will be discussed. These methods are followed by the extremely important mercuration reactions of alkanes, unsaturated hydrocarbons and aromatic compounds. The very valuable ...

The reactions of Hoppe’s lithiated carbamates with vinylboranes and boronic esters give allylic boranes/boronic esters, and subsequent addition of aldehydes provides a new route to enantioenriched homoallylic alcohols with high enantiomeric ratios and diastereomeric ratios. Specifically, reactions of spart...
