Synthesis of 3-Acyl-Isoxazoles via Radical 5-endo trig Cyclization of β,γ-Unsaturated Ketones with NaNO2

Here we report a facile cyclization reaction of β,γ-unsaturated ketones with NaNO2 under mild conditions to construct 3-acyl-isoxazoles. This transformation is realized via nitrosation of the activated methylene, radical 5-endo trig cyclization

In/InCl3-mediated cross-coupling reactions of methyl vinyl ketone with benzaldehyde in aqueous media

(matrix presented) Various β,γ-unsaturated ketones were successfully prepared by cross-coupling reactions of methyl vinyl ketone (MVK) with benzaldehydes mediated by In/InCl3 in aqueous media.

Phase Transfer Generation of Acyltetracarbonyliron Anions: their Role in the Phase Transfer Carbonylation of Reactive Halides to give Carboxylic Acids and Symmetrical and Unsymmetrical Ketones

Acyltetracarbonyliron anions RCOFe(CO)4(1-) (3) are readily synthesised under mild phase transfer (PT) conditions from pentacarbonyliron and reactive organic halides; the in situ generated anions (3) (R = ArCH2) are the true catalysts in the PT carbonylation of benzyl halides to give ketones or carboxylic acids.
