Cyclopropanation of Strained Alkenes by Palladium‐Catalyzed Reaction of 3‐Trimethylsilyl‐ or 3‐Pinacolatoboryl‐1‐arylallyl Acetates

, 2012
The palladium-catalyzed cyclopropanation of strained alkenes with 3-trimethylsilyl- or 3-pinacolatoboryl-1-arylallyl acetate derivatives is described. This reaction gives cyclopropanation products in good to high yields with a single diastereomer, and ...

A domino process for benzyne preparation: dual activation of o-(trimethylsilyl)phenols by nonafluorobutanesulfonyl fluoride.

Organic Letters, 2011
Benzynes were generated from o-(trimethylsilyl)phenols using nonafluorobutanesulfonyl fluoride (NfF) by a domino process, i.e., the nonaflation of the phenolic hydroxyl group of o-(trimethylsilyl)phenols by NfF followed by the attack of the produced ...

Expedient Synthesis of Mono-Trimethylsilyl Hydroxylamine and Bis-Trimethylsilyl Hydroxylamine

Synthetic Communications, 1985
Abstract Mono and Bis-trimethylsilylhydroxylamine are conveniently prepared by similar procedures on an arbitrarily large scale, without risk or undue effort on the part of the experimenter.

Mechanistic insights on azide-nitrile cycloadditions: on the dialkyltin oxide-trimethylsilyl azide route and a new Vilsmeier-Haack-type organocatalyst.

Journal of the American Chemical Society, 2011
The mechanism of the azide-nitrile cycloaddition mediated by the known dialkylltin oxide-trimethylsilyl azide catalyst system has been addressed through DFT calculations.

Iterative dianion relay along the ring: formation of gem-bis(trimethylsilyl) cyclopentenones from 2,5-bis(trimethylsilyl) oxy-cyclopentadienyl dianions and acid chlorides.

Chemistry, 2011
Reaction of dilithiobutadienes like (I) with aroyl chlorides containing electron-withdrawing groups (III) proceeds with C—C bond formation and double silyl shift to give gem-bis(trimethylsilyl)cyclopentenones (IV) in good yields.

Aminolysis of Bis[bis(trimethylsilyl)amido]iron and -cobalt as a Versatile Route to N-Heterocyclic Carbene Complexes

, 2011
A range of new N-heterocyclic carbene complexes of iron(II) and cobalt(II) have been conveniently obtained by the aminolysis of bis[bis(trimethylsilyl)amido]iron and -cobalt precursors with imidazol(in)ium salts.

Recent progress in Lewis base activation and control of stereoselectivity in the additions of trimethylsilyl nucleophiles.

Chemical Reviews, 2008
Trimethylsilyl nucleophiles (Me3SiNu), with silicon atoms attached to carbon, nitrogen, oxygen, or sulfur atoms, have long been recognized as effective alternatives for proton nucleophiles (HNu) in addition reactions to such electrophiles as aldehydes ...
