Asymmetric Synthesis Of Troger's Base Analogues And Studies In Molecular Recognition
(Indian Institute of Science, 2005-04-25)Troger's base was the first amine to be resolved where the chirality was due to solely very high inversion barrier around nitrogen atom. Though the molecule was known for over a century, work done during the past decade ... -
Cholic acid based new chiral auxiliaries: development and applications
(Indian Institute of Science, 2005-04-25)The thesis entitled Cholic Acid Bused New Chiral Auxiliaries: Development And Applications has been divided into three chapters. Chapter-I describes the synthesis of chiral auxiliaries (1.3) from cholic acid and Diets-Alder ... -
Combustion synthesis and properties of ferroelectrics, relaxor ferroelectrics & microwave resonator materials
Dielectric materials include ferroelectrics, relaxor ferroelectrics and microwave resonators which are classified on the basis of their dielectric performances like dielectric constant, dielectric loss and piezoelectric ... -
Dynamics of I*(2p1/2) production in the UV photodissociationof alkyl iodides
The photodissociation dynamics of alkyl iodides in their A?band of absorption (arising from n ? ?* transition) has been of interest for dynamicists for the past three decades, starting from the pioneering work of Kasper ... -
Novel layered & three-dimensional oxides of perovskite & related structures: synthesis & investigation of ion-exchange & intercalation
In this chapter, we have described the synthesis of a new series of protonated layered perovskites of the formula, HCa???La?Nb???Ti?O??, from the corresponding potassium compounds by ion-exchange. The protonated compounds ... -
Organosulfur Reactions In Organic Synthesis With Tetrathiomolybdate
(Indian Institute of Science, 2005-04-27)Recent years have seen a dramatic expansion in synthetic and structural molybdenum - sulfur chemistry. The amplest binary Mo-S moiety in MO$ ion. The thromolybdates derived by sulfur substitution from the 0x0 analogue have ... -
Studies on N-Heterocyclic Compounds
(Indian Institute of Science, 2005-04-27)The thesis entitled "Studies on N-Hetero cyclic Compounds: (a) Reaction of 5,6,7,8-Tetrahydroisoquinolines with Vilsmeier Reagent and (b) Amide Induced in situ Alkylation of 5,6-Dihydroisoquinolines" is presented in two ... -
Studies on pressed and roll-compacted alkaline iron-electrodes for nickel-iron secondary cells
It is concluded that various sulfide additives employed in this study retard passivation of the iron electrode during discharge and suppress the rate of the HER during charging. The electrodes doped with Bi?S? show minimum ... -
