Studies on Organometallic Compounds. II. Facile and Convenient Method for the Synthesis of Idoazines through Iododestannation of Trimethylstannylazines

Trimethylsatannyl and bis(trimethylstannyl) derivatives of pyridine, quinoline, and isoquinoline were prepared from the corresponding halo and dihalo (chloro or bromo) derivatives and trimethylstannyl sodium, which was generated in situ from chlorotrimethylsatannane and sodium.These stannyl derivatives readily underwent iododestannation on treatment with iodine to produce the corresponding iodo and diiodo derivatives of pyridine, quinoline, and isoquinoline, respectively, in good yields.Keywords -trimethylsannylazine; bis(trimethylstannyl)azine; iodoazine; diiodoazine; iododestannation; trimethylstannyl sodium; chlorotrimethylstannane

5-Norbornene-2-carboxylic acid: Another catalytic mediator for Catellani-type reactions

Mediators play a central role in Catellani-type reactions. Herein we reported the discovery of inexpensive 5-norbornene-2-carboxylic acid (N4) as a general catalytic mediator (20 mol%) to facilitate ortho C?H activation and the following C?C bond formation of aryl iodides. Firstly, a cooperative catalytic system comprising N4 and a palladium/XPhos complex was developed for the novel Catellani/redox-relay Heck cascade to construct tetrahydronaphthalenes and indanes that contain a quaternary carbon stereogenic center. The striking feature of this work was the avoidance of stoichiometric NBE mediator that are usually required for Catellani-type reactions. Then, preliminary results demonstrated that N4 could act as a general catalytic mediator to replace NBE for other Catellani-type reactions, which will undoubtedly inspire future developments in the field of cooperative catalysis. Finally, control experiments indicated that the carboxylic acid moiety of N4 plays an essential role in its ability to serve as a superior mediator.

Reactivity Controlling Factors for an Aromatic Carbon-Centered sigma,sigma,sigma-Triradical: The 4,5,8-Tridehydroisoquinolinium Ion

The chemical properties of the 4,5,8-tridehydroisoquinolinium ion (doublet ground state) and related mono- and biradicals were examined in the gas phase in a dual-cell Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometer. The triradical abstracted three hydrogen atoms in a consecutive manner from tetrahydrofuran (THF) and cyclohexane molecules; this demonstrates the presence of three reactive radical sites in this molecule. The high (calculated) electron affinity (EA=6.06.eV) at the radical sites makes the triradical more reactive than two related monoradicals, the 5- and 8-dehydroisoquinolinium ions (EA=4.87 and 5.06.eV, respectively), the reactivity of which is controlled predominantly by polar effects. Calculated triradical stabilization energies predict that the most reactive radical site in the triradical is not position C4, as expected based on the high EA of this radical site, but instead position C5. The latter radical site actually destabilizes the 4,8-biradical moiety, which is singlet coupled. Indeed, experimental reactivity studies show that the radical site at C5 reacts first. This explains why the triradical is not more reactive than the 4-dehydroisoquinolinium ion because the C5 site is the intrinsically least reactive of the three radical sites due to its low EA. Although both EA and spin-spin coupling play major roles in controlling the overall reactivity of the triradical, spin-spin coupling determines the relative reactivity of the three radical sites.

The selective deiodination of iodoheterocycles using the PhSiH3 – In(OAc)3 system

Nitrogen-containing pi-deficient heterocyclic iodides such as iodoquinolines or iodopyridines were deiodinated by treatment with phenylsilane catalyzed by indium acetate to give the corresponding deiodinated heterocycles at ambient temperature.

Metal-free synthesis of N-fused heterocyclic iodides via C-H functionalization mediated by tert-butylhydroperoxide

Direct, regioselective and metal-free synthesis of fused N-heterocyclic iodides is reported. This regioselective C-H functionalization is mediated by tert-butylhydroperoxide (TBHP), via dual activation of molecular iodine and a heterocyclic substrate, resulting in the in situ generation of electrophilic iodine species (I+), and free radical(s) tBuO? or tBuOO?, driving the iodination reaction.

Nickel-Catalyzed Arylative Additions on 2-Alkynyl-N-Arylsulfonylanilides to Construct Functionalized Indoles

The addition of aryl iodides to 2-alkynyl-N-sulfonylanilides to form 2,3-difunctionalized N-arylsulfonylindoles can be catalyzed using a nickel catalyst ligated to a bis(cyclohexanyl)phosphinoferrocene. A variety of nickel complexes can be used as precatalysts including a complex derived from inexpensive NiCl2¡¤6H2O. Electron-rich aryl iodides are superior partners in this transformation.

Chemical shifts and substituent chemical shift (SCS) effect are reported for 21 monosubstituted isoquinolines, carrying a halogeno, amino, piperidino or ethoxy group in position 1, 3 or 4.In some cases,assignments of 13C resonances were based on the spectra of the corresponding 5-deutero derivatives.For the fluoroisoquinolines some 13CF coupling constants are given.The 13C NMR spectra of 15 disubstituted isoquinolines were measured; with a few exceptions, mainly the 3,4- and 1,4-disubstituted isoquinolines, the chemical shifts agreed well with those calculated by addition of the SCS effects
