The metabolism of certain acids, amides and nitriles within plant tissues.
The plant growth-regulating activities of the first six members of the homologous series (2:4-dichlorophenoxy) alkanecarboxylie acids and the corresponding amides and nitriles have been assessed in the wheat cylinder, pea curvature, pea segment and tomato-leaf epinasty tests. The breakdown of these compounds when metabolized under standard conditions in wheat coleoptile and pea-stem tissues has...
متن کاملUltrasound Promoted Efficient Synthesis of some Amides from Nitriles in Ambient Condition
Some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. This new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.
متن کاملCondensation reactions and formation of amides, esters, and nitriles under hydrothermal conditions.
Hydrothermal pyrolysis experiments were performed to assess condensation (dehydration) reactions to amide, ester, and nitrile functionalities from lipid precursors. Beside product formation, organic compound alteration and stability were also evaluated. Mixtures of nonadecanoic acid, hexadecanedioic acid, or hexadecanamide with water, ammonium bicarbonate, and oxalic acid were heated at 300 deg...
متن کاملConversion of aldoximes into nitriles and amides under mild conditions.
A series of Pd(en)X2 salts were used as catalysts for the conversion of aldoximes into nitriles and amides. Highlights of this protocol include the use of inexpensive polar solvents, including water, and moderate reaction temperatures. A high degree of selectivity in the reaction outcome was observed when using aliphatic vs. aromatic/conjugated aldoximes.
متن کاملMicrobial transformation of nitriles to high-value acids or amides.
Biotransformation of nitriles mediated by nitrile-amide converting enzymes has attracted considerable attention and developed tremendously in the recent years in China since it offers a valuable alternative to traditional chemical reaction which requires harsh conditions. As a result, an upsurge of these promising enzymes (including nitrile hydratase, nitrilase and amidase) has been taking plac...
