Isocoumarins : Part V-Synthesis of 3-Methyl and 4-Carboxy-3-Methylisocoumarins

Although at room temperature, it mainly gave 4-acetyl-7-methoxyhomophthalic acid and a small amount of a drug, but at room temperature, it was mostly delivered 4-acetyl-7-dione. Depending on the temperature of the reaction, the reaction to 7-methoxy-3-methylisocoumarin became partially decarboxylated during the reaction to 7-methoxy-3-methoxy3-methylisocoumarin. The ketone cyclodehydrated to 7 methylisocoumarin and on reduction with sodium borohydride produced 7-methoxy-3-hydroxy-3,4-dihydroisocoumarin in a high yield, with sodium borohydride produced 7-methoxy-3-hydroxy-3-hydroxy-3-dihydroisocoumarin and on reduction with sodium borohydride furnished 7-methoxy-3-hydroxy-3-hydroxy-3-dihydro thia a.

A Study on the Preparation and Reactions of 2-methyl-4-dimethylarnjnobenzaldehyde

2-Methyl-4-NN-dimethylaminobenzaldehyde was prepared by formylating 2-methylaniline ming dimethyl form: 1mide and its identity were established by the manufacture of its oxime, 2:4 DNP, semiacarbazone, azine, etc. The aldehyde can be used as a reagent for the chromatographic determination of acyl glycines and the rhodanine derivative as a reagent for the detection of certain metals in Preliminary experiments.

Complexes of Uranium (VI) and Thorium (IV) with 2-Hydroxy - 5-Methyl-Acetophenone

Both conductometric and spectrophotometric techniques have been used to investigate 2-hydroxy-5-methyl acetophenone's chemistry with uranium and thorium. The stability constants of uranium and thorium complexes are estimated to be 14X 10 7 and 266x 10 2 at 30° respectively.

Hydrogen-Bonded Complexes of some Ethers with Isomeric Methyl Carbazoles

The effect of hydrogen bonding on tho near U. V. The impact of hydrogen bonding on tho near U. V. Protyl Carbazole's proton donating power of the Methyl Carbazoles rises in the order 2- Methyl Carbazole > 4- Methyl Carbazole > 1- Methyl Carbazole, i. e. , but Methyl Carbazole's base character decreases in the reverse order.

A Study on the Preparation and Reactions of p-N-Benzyl-N-Methyl Amino Benzaldehyde

Acid hydrazones were also prepared by condensing the aldehyde with different acid hydrazides. The aldehyde can be used as a reagent for the chromatographic determination of acyl glycine and the rhodanine derivative as a reagent for the detection of certain metals in Preliminary experiments.

bis (2-Hydroxy-5-methyl acetophenone oximato) dioxo Molybdenum (VI)

To investigate the composition, and stability of Mo-2-hydroxy-5-methyl acetophenone oxime, experimental and experimental techniques have been used. In this complex, the stoichiometric ratio of molybdenum and the ligand has been determined to be 1: 2 on molybdenum and the ligand. The results of chemical characterization of a pure, dry sample of the isolated complex reveal its molecular formula 2 MoO 2 A structure, which has been assigned to the complex.
