A predictive model for additions to: N -alkyl pyridiniums

Disclosed in this communication is a thorough study on the dearomative addition of organomagnesium nucleophiles to N-alkyl pyridinium electrophiles. The regiochemical outcomes have observable and predictable trends associated with the substituent patterns on the pyridinium electrophile. Often, the substituent effects can be either additive, giving high selectivities, or ablative, giving competing outcomes. Additionally, the nature of the organometallic nucleophilic component was also investigated for its role in the regioselective outcome. The effects of either reactive component are important to both the overall reactivity and site of nucleophilic addition. The utility of these observed trends is demonstrated in a concise, dearomative synthesis of a tricyclic compound shown to have insecticidal activity. This journal is

Hypervalent Iodine(III)-Catalyzed Balz–Schiemann Fluorination under Mild Conditions

An unprecedented hypervalent iodine(III) catalyzed Balz–Schiemann reaction is described. In the presence of a hypervalent iodine compound, the fluorination reaction proceeds under mild conditions (25–60 °C), and features a wide substrate scope and good functional-group compatibility.

PhenoFluorMix: Practical chemoselective deoxyfluorination of phenols

A practical deoxyfluorination with novel deoxyfluorinating reagent PhenoFluorMix, a mixture of N,N'-1,3-bis(2,6-diisopropylphenyl)chloroimidazolium chloride and CsF, is presented. PhenoFluorMix overcomes the challenges associated with hydrolysis of PhenoFluor. PhenoFluorMix does not hydrolyze, is readily available on decagram scale, and is storable in air. In this paper, we demonstrate the practicality of the reagent and exhibit the deoxyfluorination of a variety of phenols and heterocycles.

An improved catalyst system for the Pd-catalyzed fluorination of (hetero)aryl triflates

The stable Pd(0) species [(1,5-cyclooctadiene)(L·Pd)2] (L = AdBrettPhos) has been prepared and successfully evaluated as a precatalyst for the fluorination of aryl triflates derived from biologically active and heteroaryl phenols, challenging substrates for our previously reported catalyst system. Additionally, this precatalyst activates at room temperature under neutral conditions, generates 1,5-cyclooctadiene as the only byproduct, and leads to overall cleaner reaction profiles.

A General Synthesis of Substituted Fluorenones and Azafluorenones

Twenty-one variously substituted fluorenones and azafluorenones have been synthesized via photochemical Pschorr cyclizations of 2-diazoniodiaryl ketones as the key ring-forming step.Direct, (bipy)3RuII-, or (bipy)3RuII/CuII-photosensitized conditions were used, depending on the system to be cyclized.Where selectivities were possible in the ring closure, the isomer ratios obtained were in accord with an aryl radical as the reactive intermediate.The precursor aminodiaryl ketones were obtained from the sequence ortho lithiation of an arylpivalamide, reaction withan aryl aldehyde to give a 2-pivalamidodiarylcarbinol, oxidation to give a 2-pivalamidodiaryl ketone, and hydrolysis to give the 2-aminodiaryl ketone.
