Methyl Radical Initiated Kharasch and Related Reactions

An improved procedure to run halogen atom and related chalcogen group transfer radical additions is reported. The procedure relies on the thermal decomposition of di-tert-butylhyponitrite (DTBHN), a safer alternative to the explosive diacetyl peroxide, to produce highly reactive methyl radicals that can initiate the chain process. This mode of initiation generates byproducts that are either gaseous (N2) or volatile (acetone and methyl halide) thereby facilitating greatly product purification by either flash column chromatography or distillation. In addition, remarkably simple and mild reaction conditions (refluxing EtOAc during 30 minutes under normal atmosphere) and a low excess of the radical precursor reagent (2 equivalents) make this protocol particularly attractive for preparative synthetic applications. This initiation procedure has been demonstrated with a broad scope since it works efficiently to add a range of electrophilic radicals generated from iodides, bromides, selenides and xanthates over a range of unactivated terminal alkenes. A diverse set of radical trap substrates exemplifies a broad functional group tolerance. Finally, di-tert-butyl peroxyoxalate (DTBPO) is also demonstrated as alternative source of tert-butoxyl radicals to initiate these reactions under identical conditions which gives gaseous by-products (CO2).

Palladium-Catalyzed Linear Hydrothiocarbonylation of Unactivated Terminal Alkenes: Synthesis of Aliphatic Thioesters

A Pd-catalyzed hydrothiocarbonylation of unactivated terminal alkenes is presented. According to this protocol, aliphatic thioesters were synthesized with exclusive linear selectivity under mild reaction conditions. Good to excellent yields (up to 91% yie

Hydrogen-bond-assisted transition-metal-free catalytic transformation of amides to esters

The amide C-N cleavage has drawn a broad interest in synthetic chemistry, biological process and pharmaceutical industry. Transition-metal, luxury ligand or excess base were always vital to the transformation. Here, we developed a transition-metal-free hydrogen-bond-assisted esterification of amides with only catalytic amount of base. The proposed crucial role of hydrogen bonding for assisting esterification was supported by control experiments, density functional theory (DFT) calculations and kinetic studies. Besides broad substrate scopes and excellent functional groups tolerance, this base-catalyzed protocol complements the conventional transition-metal-catalyzed esterification of amides and provides a new pathway to catalytic cleavage of amide C-N bonds for organic synthesis and pharmaceutical industry.

Cyclopropanation of Terminal Alkenes through Sequential Atom-Transfer Radical Addition/1,3-Elimination

An operationally simple method to affect an atom-transfer radical addition of commercially available ICH2Bpin to terminal alkenes has been developed. The intermediate iodide can be transformed in a one-pot process into the corresponding cyclopropane upon treatment with a fluoride source. This method is highly selective for the cyclopropanation of unactivated terminal alkenes over non-terminal alkenes and electron-deficient alkenes. Due to the mildness of the procedure, a wide range of functional groups such as esters, amides, alcohols, ketones, and vinylic cyclopropanes are well tolerated.

The synthesis of 11-[(2-pyridyl)amino]- and 11-[(9-anthracenylcarbonyl) amino]undecyl phosphate and the study of their acceptor properties in the enzymatic reaction catalyzed by Salmonella galactosyl phosphotransferases

Undecyl phosphate derivatives with new fluorescent labels, 11-[(2-pyridyl)amino]undecyl phosphate and 11-[(9-anthracenylcarbonyl)amino] undecyl phosphate, were synthesized. These compounds were shown to be acceptor substrates of the galactosyl phosphate r

The catalytic isomerization of terminal carbon-carbon double bonds in liquid crystalline polyesters at hydrosilation with 1-(1′-arylethoxy)-1,1, 3,3-tetramethyl disiloxanes

In the present article, we report on the synthesis and investigation of the hydrosilylation of liquid crystalline compounds with terminal carbon-carbon double bonds in aliphatic tails mediated by complexes of rhodium (I) and platinum (II). New liquid crystalline compounds based on terephthaloyl-bis-4- oxybenzoate with terminal carbon-carbon double bonds in aliphatic tails were synthesized. The introduction in aliphatic tails of polar and light polarizible fragments lead to a decrease of mesomorphogenic ability-resulting compounds. The hydrosilylation of liquid crystalline compounds with terminal carbon-carbon double bonds in aliphatic tails with 1-(1′-arylethoxy)-1,1,3,3-tetramethyl disiloxanes mediated by complexes of rhodium (I) and platinum (II) was investigated. The main process in these conditions was the isomerization of olefin fragments. Copyright Taylor & Francis Group, LLC.

Catalytic isomerization of terminal olefins in liquid-crystalline polyesters at hydrosilylation with 1-(1'-arylethoxy)-1,1,3,3- tetramethyldisiloxanes

Liquid-crystalline compounds based on terephthaloyl-bis(4-oxybenzoates) with terminal double carbon-carbon bonds in aliphatic fragments were prepared. The introduction of polar and easily polarizable groups into the aliphatic fragments was shown to reduce the mesomorphic capacity. Hydrosilylation of the polyesters catalyzed by rhodium and platinum complexes was studied. The isomerization of the olefin fragment was demonstrated to be the main process.
