Selective synthesis of iminodioxaspirononanes and diazaspirononanes using formic acid-activated Mn(III) oxidation of N1,N3-disubstitued malonamides with 1,1-diarylethenes

The Mn(III)-based oxidation of N1,N3-disubstituted malonamides with alkenes by Kurosawa spirolactonization using malonic acid afforded iminodihydrofurans. A similar reaction with Mn(OAc)3, which was activated by HCO2

Photoinduced Hydroarylation and Cyclization of Alkenes with Luminescent Platinum(II) Complexes

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron-deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible-light (410 nm) irradiation, affording anti-Markovnikov hydroarylated compounds in up to 95 % yield. Besides, a protocol for [Pt(O^N^C^N)]-catalyzed intramolecular photocyclization of acrylanilides to give structurally diverse 3,4-dihydroquinolinones has been developed.

Visible-Light-Induced Meerwein Fluoroarylation of Styrenes

An unprecedented approach for assembling a broad range of 1,2-diarylethane derivatives with fluorine-containing fully substituted carbon centers was developed. The protocol features straightforward operation, proceeds under metal-free condition, and accommodates a large variety of synthetically useful functionalities. The critical aspect to the success of this novel transformation lies in using aryldiazonium salts as both aryl radical progenitor and also as single electron acceptor which elegantly enables a radical-polar crossover manifold.
