Addition-type oxidation of silylalkene using ozone: An efficient approach for acyloin and its derivatives

Igawa, Kazunobu,Kawasaki, Yuuya,Tomooka, Katsuhiko

, p. 233 - 235 (2011/05/14)

Acyloins are efficiently synthesized in three steps from alkynes via ydrosilylation followed by an addition-type ozone oxidation and hydrogenation. The key intermediate α-silylperoxy ketone is convertible to not only acyloin but also O-silylated acyloin and diketone.
