T. Honda et M. Katoh, TRIMETHYLSILYL CHLORIDE-ACCELERATED REDUCTION AND PINACOL COUPLING OFCARBONYL-COMPOUNDS BY MEANS OF SAMARIUM DIIODIDE, Chemical communications, (4), 1997, pp. 369-370
The combination of samarium diiodide (SmI2) and trimethylsilyl chlorid
e (Me(3)SiCl) in THF-HMPA is found to accelerate the reduction of ster
ically hindered and enolisable ketones, and also to accelerate pinacol
isation of the carbonyl compounds depending on the reaction conditions
.
