PROCESS FOR THE PREPARATION OF HETEROCYCLIC ALDEHYDES |
| 摘要 |
Heterocyclic aldehydes having the formula (I), in which A, B stand for possibly substituted methylene groups; m, n = 1 to 5 and m+n > 2, are prepared by hydrogenating carboxylic acids having the formula (IIa) or their esters (IIb) derived from C1-C10 alcohols at 200 to 450 ~C in the presence of a catalyst. The products thus obtained are useful as precursors of cyclohexenone type herbicides.
