Abstract

The reaction of benzyl chloride with isopropoxy-pinacolatoborane (iPrOBpin) in the presence of sodium dispersion (SD) afforded benzylborane in a quantitative yield, in which undesired dimerization of benzyl chloride was almost completely suppressed (<2%). The formation of related benzylic stannane, silane also proceeded with SD. Several benzylic halides were transformed into the corresponding boranes in a similar manner up to 94% yield.
