2-Acylfuran derivatives ##STR1## (R: alkyl, phenyl, etc.; R.sub.1 : H, alkyl) are prepared in high yield by reaction, in the presence of a boron trifluoride complex catalyst, of a furan compound ##STR2## (X: H, Cl, Br; Y: Cl, Br) or with RCOOH in the presence of (XYCHCO).sub.2 O.
2-酰基呋喃衍生物##STR1##(R:烷基,苯基,等;R.sub.1:H,烷基)在硼三氟化物复合催化剂存在下,通过呋喃化合物##STR2##(X:H,Cl,Br;Y:Cl,Br)的反应高产率制备,或者在(XYCHCO).sub.2 O存在下与RCOOH反应。
