Rukhsana I. Kureshy,Irshad Ahmad,Noor-ul H. Khan,Sayed H.R. Abdi,Kavita Pathak,Raksh V. Jasra +5 more
TL;DR: In this paper, a chiral Mn(III) salen complex supported onto modified mesoporous supports (MCM-41 and SBA-15) was prepared using 3-aminopropyltriethoxysilane as a reactive surface modifier by a covalent grafting method.
Journal ArticleDOI
Metal catalyzed asymmetric cyanation reactions
TL;DR: In this article, the authors discuss the various methods for catalytic asymmetric synthesis of cyanohydrins derived from both aldehydes and ketones using different sources of cyanide.
Journal ArticleDOI
Synthesis, characterization, and EPR studies of stable ruthenium(III) Schiff base chloro and carbonyl complexes
TL;DR: In this paper, the oxidation state of the metal ion in these complexes is confirmed to be +3 by electrochemical, magnetic susceptibility, and EPR measurements using elemental analysis and IR, UV-visible, differential-pulse polarography.
Journal ArticleDOI
Dicationic chiral Mn(III) salen complex exchanged in the interlayers of montmorillonite clay: a heterogeneous enantioselective catalyst for epoxidation of nonfunctionalized alkenes
Rukhsana I. Kureshy,Noor-ul H. Khan,Sayed H.R. Abdi,Irshad Ahmad,Surendra Singh,Raksh V. Jasra +5 more
TL;DR: In this article, a chiral MnIII salen complexes 1−4 were obtained from the reaction of 1S,2S-(+)-1,2-diaminocyclohexane/1S, 2S-(−)-diphenyldiamine with 2-hydroxy-3-t-Bu-5-(triisooctylaminomethyl) benzaldehyde chloride/2-hydroxyl-3t-bu-5-branched-benzaldehyde chloride and were exchanged in montmorillonite clay
Journal ArticleDOI
Enantioselective epoxidation of non-functionalised alkenes using a urea–hydrogen peroxide oxidant and a dimeric homochiral Mn(III)-Schiff base complex catalyst
TL;DR: The catalytic enantioselective epoxidation of chromenes, indene and styrene using a urea-hydrogen peroxide adduct as an oxidising agent and the novel dimeric homochiral Mn(III)-Schiff base catalyst 1 has been investigated in the presence of carboxylate salts and nitrogen and oxygen coordinating co-catalysts as mentioned in this paper.
