Abstract (en)

[origin: DE10010594A1] Production of chloroalkanoyl chlorides (I) with a (substituted) 1-10 carbon (hetero)alkylene chain, by reacting a lactone (II) with a chlorinating agent in the presence of a chlorination catalyst, is carried out in the presence of a boron compound. Production of chloroalkanoyl chlorides of formula (I) with a (substituted) 1-10 carbon (hetero)alkylene chain, by reacting a lactone of formula (II) with a chlorinating agent in the presence of a chlorination catalyst, is carried out in the presence of a boron compound. [Image] R1>, R2>H or R; R : halo, nitro, cyano or an organic group containing carbon; Y : optionally R-substituted 1-10 C alkylene, which may have a (thio)ether, tertiary amino or keto group in the chain; and R groups on Y, R1> and/or R2>can be linked to form a non-aromatic system.
