___________________________________________________________________________________________ Abstract Although iron was known and widely used by people for hundreds of years, Grignard reagents also used for about a century, binding together these two concepts still took a long time and surprisingly it did not become a hot topic in chemistry until this decade. This paper is presenting several dev...
متن کاملCascade radical reaction of substrates with a carbon–carbon triple bond as a radical acceptor
The limitation of hydroxamate ester as a chiral Lewis acid coordination moiety was first shown in an intermolecular reaction involving a radical addition and sequential allylation processes. Next, the effect of hydroxamate ester was studied in the cascade addition-cyclization-trapping reaction of substrates with a carbon-carbon triple bond as a radical acceptor. When substrates with a methacryl...
متن کاملPreparation of fused polycyclic vinylcyclopropanes via radical cascade reactions.
Radical cascades employing (dichloromethyl)dimethylsilyl ethers as both a point of radical initiation and termination, allow efficient entry to fused polycyclic cyclopropanes, and are also suitable for the design of other radical processes terminated by beta-elimination of chloride.
متن کاملSynthesis and carbon-carbon bond-forming reactions of tungsten, molybdenum, and rhenium enolates
Alkylation of sodium cyclopentadienyl(tricarbonyl)metal— lates of tungsten and molybdenum with o—chloro ketones and c—chloro esters gives stable tungsten and molybdenum enolates (23a—23d). Similar alkylation of sodium pentacarbonylrhenate provides rhenium enolates 24. Compounds 23 lOse carbon monoxide and rearrange to 3—oxaallyl complexes 25 upon irradia— tiøn. Compounds 25 react with benzaldeh...
متن کاملCarbon-carbon bond forming reactions with substrates absorbed non-covalently on a cellulose chromatography paper support.
Reactions and purifications, including carbon-carbon bond forming reactions, can be carried out on a cellulose support on which the substrates are non-covalently absorbed.
