Abstract The reaction of [Ag(PPh 3 ) 3 Cl] 1 with SnCl 2 followed by recrystallization of the product led to the isolation of tetrameric chloro(triphenylphosphine)silver(I) [Ag 4 (PPh 3 ) 4 Cl 4 ] 2 . The dual reagent combination of 2 -SnCl 2 show moderate catalytic activity in multicomponent coupling reactions involving C H activation.

Abstract Mercury is one of the elements which had attracted the attention of the chemists and physicians of ancient India and China. Among the various metal based drugs which utilize mercury, we became interested in the red sulfide of mercury which is known in ancient Indian literature as rasasindur (alias rasasindura, rasasindoor, rasasinduram, sindur, or sindoor) and is used extensively in various ailments and diseases. Following various physico-chemical characterizations it is concluded that ...

Abstract Flow chemistry enables the preparation of bis(indolyl)methanes from various indoles and structurally divergent aldehydes using Sc(OTf) 3 catalysis. The reaction is regioselective for C-3 functionalization of the indoles, occurring over short reaction times allowing for rapid investigation of scope with straightforward work up facilitating product isolation.

A Ni(OAc)2/Ag(OTf) catalysed coupling of aryl alkynes and propargylic alcohol/ether/ester gave the corresponding unsymmetrical 1,3-diynes in good to excellent yields. The reaction does not require bases, ligands or additives and shows excellent hetero-selectivity, thereby addressing the current challenges in the field of coupling of two different terminal alkynes.

AbstractAdvances in the field of mechanical activation of Al-oxyhydroxide minerals (synthetic as well as in natural bauxites) over the years around the globe are described in this review. An overview of fundamental aspects of mechanical activation with select examples of applications/examples in extractive metallurgy preludes the theme, mechanical activation of Al-oxyhydroxides. The focus is primarily on mechanically induced reactivity of largely used (and most commonly available too) Al-oxyhydr...

Abstract Using a combination of density functional theory and many-body GW corrections, we calculate the quasiparticle band gap of bulk α -HgS and investigate the effect of quantum confinement on the geometric, electronic and optical structures. The basic structural unit of α -HgS is a one-dimensional helical chain consisting of covalently bound Hg and S atoms. When isolated to just a single helix or to a few-helix configuration, we find that α -HgS becomes a wide-gap semiconductor with a quasip...

Abstract Facile insertion reaction of SnCl 2 across pentamethylcyclopentadienyl complexes of Ir(III) and Rh(III) resulted in the formation of Ir–SnCl 3 and Rh–SnCl 3 heterobimetallic complexes. Treatment of SnCl 2 with [Cp*IrCl 2 ] 2 and [Cp*Ir(NH 2 t Bu)Cl 2 ] afforded [Cp*Ir(SnCl 3 ) 2 {SnCl 2 (H 2 O) 2 }] ( 1 ) and [Cp*Ir(SnCl 3 ) 3 ][NH 3 t Bu] ( 3 ), respectively. Similarities in NMR data for complexes 1 and 3 suggested that complex 1 converts to anionic [Cp*Ir(SnCl 3 ) 3 ] species in solut...

Abstract An atom economic and catalytic substitution reaction of π-activated alcohols by a multimetallic Ir–Sn 3 complex has been demonstrated. The multimetallic Ir–Sn 3 complex can be easily synthesized from the reaction between [Cp ∗ IrCl 2 ] 2 and SnCl 2 . In presence of as little as 1 mol % of the catalyst three different types of π-activated alcohols, namely benzyl, allyl, and propargyl alcohols, have been successfully transformed into alkylated products using carbon (arenes, heteroarenes, ...
