Synthesis and reactivity of dimolybdathiaborane cluster [(Cp∗Mo)2B4SH6] (Cp∗ = η 5-C5Me5)
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 123 - Trang 847-851 - 2011
Chemistry and reactivity of dimolybdathiaborane, [(Cp∗Mo)2B4SH6], 1, obtained from the reaction of 2-mercaptobenzothiazole, [Cp∗MoCl4] and [LiBH4.thf], has been explored with dinuclear metal carbonyl [Fe2(CO)9]. As a result, reaction of 1 with [Fe2(CO)9] yielded heterometallathiaborane, [(Cp∗Mo)2B4H6SFe(CO)3], 2 in good yield. Both the new compounds have been characterized in solution by 1H, 11B a......
The optical properties of titanium dioxide
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 35 - Trang 117-125 - 1952
Dispersion formulæ valid in the visible region are offered for rutile, anatase and brookite. These incorporate a characteristic frequency at 2870 Å in all the cases. The value ofdn/dt in the three crystals are explained by large transfers of transition probability and moderate shifts towards large wave-lengths of this frequency as the temperature is raised. In addition, a calculation is made of th......
Kinetic studies in ester hydrolysis
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 32 - Trang 85-94 - 1950
The kinetics of the hydrolysis of ethyl acetate in acetone-water and dioxane-water systems are reported. The rate constant passes through a minimum when the concentration of the organic solvent in the medium is in the neighbourhood of 80%. The temperature variation conforms strictly to the Arrhenius equation even for media containing extremely high proportions of organic solvent. Even though the a......
Facile one-pot synthesis of functionalized organophosphonate esters via ketone insertion into bulky arylphosphites
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 120 - Trang 131-136 - 2008
The reaction of phosphorus trichloride with 2,6-diisopropyl phenol in the presence of LiCl under reflux conditions for 24 h produces a mixture of (ArO)PCl2 and (ArO)2PCl (Ar = 2,6-iPr2C6H3). The hydrolysis of the aryloxy compounds in acetone/H2O results in the formation of two novel phosphonate ester derivatives [(ArO)P(O)(OH)(CMe2OH)] (1) and [(ArO)2P(O)(CMe2OH)] (2), respectively in a moderate y......
Hysteresis in sorption—X
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 17 - Trang 46-49 - 1943
In a system of closely packed spherical particles, formation of two different types of capillaries cavities and open pores—is indicated. Assuming spherical particles of equiradius, the volume of an open pore is calculated in relation to particle radius. The total open pore is calculated in relation to particle radius. The total open pore volume just as the total cavity volume, decreases as the par......
On some integral properties of hypergeometric functions
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 74 - Trang 189-194 - 1971
In this note certain integrals involving hypergeometric functions have been evaluated in convenient and elegant forms.
A remark on the paper of Dwivedi
Proceedings of the Indian Academy of Sciences - Chemical Sciences - Tập 85 - Trang 186-190 - 1977
In the present paper the method of Dwivedi and Trivedi in solving the dual integral equations, has been modified by presenting a very comprehensive and lucid solution, based on the analysis suggested by Fox.
