Microbial transformation of esters of chlorinated carboxylic acids.
Two groups of compounds were selected for microbial transformation studies. In the first group were carboxylic acid esters having a fixed aromatic moiety and an increasing length of the alkyl component. Ethyl esters of chlorine-substituted carboxylic acids were in the second group. Microorganisms from environmental waters and a pure culture of Pseudomonas putida U were used. The bacterial popul...
متن کاملMicrobial reduction of aromatic carboxylic acids.
Several benzoic, cinnamic and phenylacetic acid derivatives were screened with 20 micro-organisms, mainly fungi, for the reduction of their carboxylic function. For all organisms several compounds were reduced in fairly good yields up to 80% to the corresponding alcohol. No general rule could be established, concerning the substitution pattern, as to which compounds were transformed to the alco...
متن کاملIron-catalysed green synthesis of carboxylic esters by the intermolecular addition of carboxylic acids to alkenes.
Iron triflate, in situ-formed from FeCl3 and triflic acid, or FeCl3 and silver triflate efficiently catalyse the intermolecular addition of carboxylic acids to various alkenes to yield carboxylic esters; the reaction is applicable to the synthesis of unstable esters, such as acrylates.
متن کاملMicrobial transformation of chlorinated benzenes under anaerobic conditions.
Chlorobenzenes are reductively dechlorinated by anaerobic bacterial cultures obtained from sediments and sludge. Recently a strain was isolated that couples reductive dechlorination of chlorobenzenes with energy conservation. The results reviewed in this article suggest that additional anaerobic bacteria, thriving by dehalogenation of chlorobenzenes or chlorobiphenylic compounds, can be isolated.
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
