Indium-mediated regioselective Markovnikov allylation of unactivated terminal alkynes

Allylation of unactivated terminal alkynes by a simple treatment with allyl bromide and indium metal in THF at room temperature produces 1,4-dienes via regioselective Marknovnikov addition

Indium triiodide catalysed one-step conversion of tetrahydropyranyl ethers to acetates with high selectivity

A very simple and efficient method has been developed for the chemoselective one-step conversion of tetrahydropyranyl ethers of primary alcohols to the corresponding acetates through an indium triiodide catalysed transesterification process in ethyl acetate

Highly selective one-pot conversion of THP and MOM ethers to acetates by indium triiodide-catalysed deprotection and subsequent transesterification by ethyl acetate

A simple and efficient method is developed for the chemoselective one-pot conversion of tetrahydropyranyl (THP) and methoxymethyl (MOM) ethers of primary alcohols to the corresponding acetates by indium triiodide-catalysed deprotection and subsequent acetylation by ethyl acetate through a transesterification process

Selective monoacylation of ferrocene. An eco-friendly procedure on the solid phase of alumina

A simple, efficient and environment-friendly procedure has been developed for acylation of ferrocene with direct use of carboxylic acid in the presence of trifluoroacetic anhydride on the solid phase of alumina. A wide range of structurally varied carboxylic acids have been found to provide selectively the monoacylated products in high yields

Indium as a reducing agent. Chemoselective reduction of α-halocarbonyl compounds and benzyl halides by indium metal in water under sonication

Indium metal in water reduces α -halocarbonyl compounds and benzyl iodides to the corresponding dehalogenated products in excellent yields under sonication although simple alkyl and aryl iodides remained inert under these conditions

Highly selective acylation of alcohols and amines by an indium triiodide-catalysed transesterification process

A very simple method has been developed for the acylation of alcohols and amines by ethyl acetate through an indium triiodide-catalysed transesterification process. Using this method acylation of a primary OH group in the presence of secondary and phenolic OH groups, and of a primary NH2 in the presence of secondary NH and primary OH have been achieved with high selectivity

Catalysis by ionic liquids: solvent-free efficient transthioacetalisation of acetals by molten tetrabutylammonium bromide

Tetrabutylammonium bromide in molten state has been demonstrated to be a very efficient and recyclable catalyst for transthioacetalisation of O,O-acetals to S,S-acetals under solvent-free conditions

Solvent-free, catalyst-free Michael-type addition of amines to electron-deficient alkenes

A variety of amines undergo Michael-type additions to α,β-unsaturated nitriles, carboxylic ester and ketones in a neat mixture without any solvent and catalyst to produce the corresponding β-amino derivatives in excellent yields

Indium(III) chloride - catalyzed Michael addition of thiols to chalcones: a remarkable solvent effect

Indium(III) chloride in methanol efficiently catalyzes Michael addition of aromatic and aliphatic thiols to chalcones and related compounds. This reaction is remarkably solvent selective and it does not proceed in conventional solvents such as tetrahydrofuran, methylene chloride and water

Stereospecific synthesis of endo-6-aryl-2-oxobicyclo [3.3.1]nonanes

Two alternate synthetic routes to endo-6-aryl-2-oxobicyclo 3.3.1 nonan [3a-d] by sterespecific catalytic hydrogenetion of the easily accessible 6-arylbicyclo 3.3.1 nona-3,6-dien-2-ones [2a-d], and regioselective oomologation of endo-2-aryl-6-oxobicycle 3.2.1 octanes [4a-d] are described
