- Palladium on manganese ferrite: An efficient catalyst for one pot synthesis of primary amides from iodobenzene
-
Amidation of aryl iodide in one pot is reported using Pd-MnFe2O4 as a catalyst. The catalyst was characterized by various techniques such as XRD, FEG-SEM, EDS, TEM, BET surface area and ICP AES. K4[Fe(CN)6]is used as a non toxic cyanation reagent for in situ generation of benzonitrile and hydrolyzed as soon as it formed. The catalyst was found to be efficient and can be used for several cycles without loss in activity. Good to excellent yields of primary amides were obtained.

The present invention relates to a compound represented by the following formula, a pharmacologically acceptable salt thereof, or a use thereof as a pharmaceutical: wherein R1 and R2 are substituents adjacent to each other, and together with two carbon atoms to each of which they attach, form a 5- to 7-membered non-aromatic carbocyclic group or the like, which may be substituted by 1 to 4 substituents selected from (1) an oxo group, (2) a hydroxyl group, and the like; R3 represents a hydrogen atom or the like; and R6 represents a hydrogen atom or the like. It is an object of the present invention to discover an agent for treating or preventing lower urinary tract symptoms, and particularly symptoms regarding urinary storage, which has a superior strength of binding to a 5-HT1A receptor and an antagonism to the receptor.

- Labelled compounds of interest as antitumour agents - VI. Isotopically efficient syntheses of [15N]-nitrothiophenecarboxamides
-
Reaction of 3-cyanothiophene with one equivalent of potassium nitrate in concentrated sulphuric acid causes nitration, concurrent with hydrolysis of the nitrile, to give 5-nitro-thiophene-3-carboxamide in high yield. Similarly, 2-cyanothiophene gives 4-nitro-thiophene-2-carboxamide and 5-nitrothiophene-2-carboxamide, benzonitrile gives 3-nitrobenzamide and 4-methylbenzonitrile gives 4-methyl-3-nitrobenzamide. Extension of this process to use of potassium [15N]-nitrate, formed from [15N]-nitric acid (95% isotopic enrichment), enables preparation of the corresponding [15N]-nitrothiophenecarboxamides in high isotopic yield.
