PROCESS FOR PREPARING ALDEHYDES |
摘要 |
A process for preparing an aldehyde or aldehydes represented by the following formula (III), characterized in that a diaryliodonium salt represented by the following formula (I) is reacted with an unsaturated alcohol represented by the following formula (II) in a solvent containing a base in the presence of a transition metal catalyst at a temperature in the range of room temperature to 100 DEG C:
[Ar1-I<(+)>-Ar2]X<(-)> (I)
CHR1 = CR2 -CH2OH (II)
Ar3-CHR1-CHR2-CHO (III)
wherein Ar1 and Ar2, which may be alike or different, are each an aryl group which may have a substituent group or groups, X<(-)> is a counter ion which is inert to the above reaction, Ar3 is the same aryl group as Ar1 or Ar2, and R1 and R2 are each hydrogen atom or an alkyl group of C1 to C12. |
