Silica gel-mediated hydrochlorination of unactivated alkenes using 35% hydrochloric acid underorganicsolvent-freeconditions proceeded to give the corresponding chlorides in good yields. Hydrobromination or hydriodination using 47% hydrobromic acid or 55% hydriodic acid afforded the corresponding halides, respectively. Silica gel could be recycled five times without any significant loss of activities

Dialkylzinccompounds react with tertiaryalkylhalides to afford the corresponding coupling products containing a quaternary carbon atom, thereby making geminal dialkylation of ketones or hydroalkylation of olefins possible.

The generality of light initiated halogenative decarboxylation of thiohydroxamic esters was studied. This method gave high yields of alkyl chlorides, bromides and iodides derivedfrom primary, secondary and tertiairy substituted carboxylic acids.

The hydrochlorination of a series of simple and functionalized olefins in high yields was readily accomplished using a mixture of trimethylchlorosilane and water. Hydrochlorination by this procedure is chemoselective and regioselective.
