Surface-Functionalized COMB Capacitive Sensors and CMOS Electronics for Vapor Trace Detection of Explosives
In this paper, we present a miniature detection system, which is able to detect and selectively recognize different vapor traces of explosives. It is based on surface-functionalized array of COMB
Ligand-free palladium-catalysed direct arylation of heteroaromatics using low catalyst loadings.
This work reports on ligandless palladium-catalysed direct arylation of heteroaromatics using low catalyst loadings, which provides a cost-effective and environmentally attractive procedure for the preparation of arylated heteroARomatics.
Ligand-free palladium-catalyzed direct arylation of thiazoles at low catalyst loadings.
Ligand-free Pd(OAc)2 was found to catalyze very efficiently the direct arylation of thiazole derivatives under very low catalyst concentration. By using activated aryl bromides, the reaction can be
Metal-Catalysed Transfer Hydrogenation of Ketones
The focus of this review is devoted to chiral catalyst types which are capable of inducing high stereoselectivities, and Ruthenium complexes still represent the largest part of the catalysts, but other metals are rapidly penetrating this field.
Low catalyst loading ligand-free palladium-catalyzed direct arylation of furans: an economically and environmentally attractive access to 5-arylfurans
The direct 5-arylation of furans at very low catalyst loading using Pd(OAc)2 as catalyst without added ligand proceed in high yields. Turnover numbers up to 10000 have been obtained for the coupling
Ligand-less palladium-catalyzed direct 5-arylation of thiophenes at low catalyst loadings
Ligand-less Pd(OAc)2 provides a very efficient catalyst for the direct 5-arylation of thiophene derivatives. With this catalyst, a low palladium concentration (0.1–0.001 mol%) should be employed in
Ruthenium(II) Acetate Catalyst for Direct Functionalisation of sp2-CH Bonds with Aryl Chlorides and Access to Tris- Heterocyclic Molecules
The in situ generated (p-cymene)ruthenium diacetate [Ru(OAc) 2 (p-cymene)] catalyst 2, prepared from the (p-cymene)ruthenium dichloride dimer {[RuCl 2 ( P -cymene)]2, 1} and potassium acetate (KOAc),
Advances in Catalyst Systems for the Asymmetric Hydrogenation and Transfer Hydrogenation of Ketones
Hydrogenation of prochiral ketones using chiral transition-metal catalysts represents the cleanest way to access enantiomerically enriched secondary alcohols, which are important building blocks in
Synthesis and Reactivity of 2‐Arylquinazoline Halidoruthenacycles in Arylation Reactions
The synthesis of a range of new cyclometallated organoruthenium(II) complexes through the ortho‐C−H activation of the aryl group in 2‐aryl‐substituted quinazolines with [RuX2(p‐cymene)]2 is
Antioxidant activity of natural and modified phenolic extracts from Satureja montana L.
Abstract Satureja montana L. is an aromatic plant from Mediterranean area, which possess wide spectrum of different biological activities. Phenolic-rich extracts from S. montana were obtained by
