リンハロゲン化物による2-フェニルチオ-及び2-エトキシ-アリルアルコール及びその誘導体のアルデヒド, ケトンへの異性化反応

抄録

2-Phenylthioallyl alcohol and its derivatives (1) are selectively rearranged to the corresponding aldehydes or ketones (2) in the presence of phosphorus tribromide, triphenylphosphine dibromide, or thionyl chloride without the formation of halogenated products. Similarly, the carbonyl compounds, (4), (5) and (6) are obtained from 2-ethoxypropenol (3), being different from the 2-trimethylsilylpropenol (8) which is readily halogenated to (9).
