The thermally initiated reaction of hexafluorobut-2-yne with (π-C5H5)Rh(CO)2 has been studied in detail, and it is found that the nature and yields of the products are sensitive to the reaction conditions. The known complexes (π-C5H5)Rh-[(C4F6)2CO] and (π-C5H5)Rh(C4F6)3 and the new organorhodium complexes (π-C5H5)2Rh2(CO)2(C4F6), (.π-C5Hs)3Rh3(C4F6)2, (π-C5H5)2Rh2(CO)(C4F6)2, and (π-C5H5)3Rh3(CO)(C4F6) have been isolated from the reaction system. Each organorhodium complex has been characterized by elementary and mass spectral analysis, and reasonable structures for all complexes have been predicted from the appropriate i.r. and N.M.R. data. The monoalkyne complex (π-C5H5)2Rh2(CO)2(C4F6) is an intermediate in the formation of the other organorhodium complexes.

A series of 3-substitutedphenyl-1-thia-tetrazopentaleno[1,2-b] naphthalene4(a-d)and 2-substitutedphenyl-1-thia-pentazopentaleno[1,2-b] naphthalene5(a-d)were synthesizedvia., the reaction of 2-aminothiazoles2(a-d)and 2-aminothiadiazoles3(a-d)with 2,3-dichloro quinoxaline1in ionic liquid without using any catalyst. This protocol has the advantages of easier workup, milder reaction conditions, high yields, and environmentally benign procedure over traditional methods. The synthesized compounds4(a-d)and5(a-d)tested for their anti-fungal activity and these compounds were characterized by IR, NMR and Mass spectral analysis.

Benzothiazole Derivatives

Objective: The objective of this study was to synthesize and evaluate the anthelmintic activity (AA) of novel benzothiazole derivatives containing indole moieties (BDIM). Methods: The present works which involve the substituted isatin Schiff bases undergo acetylating and reacting with 2-aminobenzothiazole to give novel BDIM. Results: All the newly synthesized molecules (5a-5o) were characterized by Fourier-transform infrared spectroscopy, H_nuclear magnetic resonance, and mass spectral analysis along with physical data. The biological potentials of the newly synthesized compounds are evaluated for their AA using an Indian earthworm (Pheretima posthuma), and albendazole was used as standard drug. Conclusion: The synthesized compound 5f, 5n, and 5o showed good AA, whereas others exhibited significant activities.
