Cerium Chloride Catalyzed, 2-Iodoxybenzoic Acid Mediated Oxidative Dehydrogenation of Multiple Heterocycles at Room Temperature

Catalytic cerium chloride was found to activate 2-iodoxybenzoic acid (IBX) for the oxidative dehydrogenation of tetrahydroisoquinolines, tetrahydro-beta-carbolines, and thiazolidines to their dehydrogenated and aromatic forms at room temperature in moderate to excellent yields. The robustness of the protocol was demonstrated by scaling up the reactions to multigram quantities.

Reactions of group III biheterocyclic complexes

Group III alkyl complexes supported by a ferrocene diamide ligand (1,1?-fc(NSitBuMe2)2) have been found to be reactive toward aromatic N-heterocycles such as 1-methylimidazole and pyridines. These reactions were investigated experimentally and computationally. An initial C-H activation event is followed by a coupling reaction to form biheterocyclic complexes, in which one of the rings is dearomatized. In the case of 1-methylimidazole, the biheterocyclic compound could not be isolated and further led to an imidazole ring-opened product; in the case of pyridines, it transformed into an isomer with extended conjugation of double bonds. Mechanisms for both reactions are proposed on the basis of experimental and computational results. DFT calculations were also used to show that an energetically accessible pathway for the ring-opening of pyridines exists.

Ammonium formate/palladium on carbon was found to be a convenient system for selective reduction, in good yields, of the heterocyclic ring in quinoline and isoquinoline derivatives.

A comparison of some pyrolysis reactions of benzotriazoles, benzisoxazolones and benzisothiazolones

The products of flash vacuum pyrolysis of N-acetyl, N-methyl, N-benzyl and N-heteroaryl-substituted benzotriazole, 2,1-benzoxazol-3-one and 2,1-benzothiazol-3-one have been compared. The pyrolysis of benzotriazoles and benzisoxazolones appears to involve an iminocarbene intermediate, although the N-benzyl analogues react by radical pathways. Benzisothiazolones appear to form iminoketene intermediates.

Anhydrous Tetramethylammonium Fluoride for Room-Temperature SNAr Fluorination

This paper describes the room-temperature SNAr fluorination of aryl halides and nitroarenes using anhydrous tetramethylammonium fluoride (NMe4F). This reagent effectively converts aryl-X (X = Cl, Br, I, NO2, OTf) to aryl-F under mild conditions (often room temperature). Substrates for this reaction include electron-deficient heteroaromatics (22 examples) and arenes (5 examples). The relative rates of the reactions vary with X as well as with the structure of the substrate. However, in general, substrates bearing X = NO2 or Br react fastest. In all cases examined, the yields of these reactions are comparable to or better than those obtained with CsF at elevated temperatures (i.e., more traditional halex fluorination conditions). The reactions also afford comparable yields on scales ranging from 100 mg to 10 g. A cost analysis is presented, which shows that fluorination with NMe4F is generally more cost-effective than fluorination with CsF.

Lanthanides and actinides: Annual survey of their organometallic chemistry covering the year 2015

This review summarizes the progress in organo-f-element chemistry during the year 2015. The year 2015 witnessed a slight increase of contributions in the fields of organolanthanide and organoactinide chemistry over 2014 (ca. 10% more). A continuing trend for many years which continued into 2015 was the investigation of highly reactive lanthanide alkyl complexes supported by non-cyclopentadienyl ligands (e.g. amidinates, beta-diketiminates etc.). Many of these complexes found useful applications in homogeneous catalysis. Trinuclear rare-earth metal methylidene (CH22-) complexes are an emerging class of compounds that serve as methylidene transfer agents for the methylenation of carbonyl compounds. The range of rare-earth metal alkyl complexes bearing different types of carbene ligands have also been further expanded. Several new lanthanide phosphido and phosphinidene complexes have been stabilized by specially designed N,N’-chelating ligands. The range of fully characterized lanthanide(II) compounds of the type [K(2.2.2-cryptand)][Cp’3Ln] (Cp’=C5H4SiMe3) has again been significantly expanded so that the +2 ions are now available for yttrium and all the lanthanides (except promethium, which was not studied due to its high radioactivity). The first well-defined lutetacyclopentadienes have been synthesized and their reactivity has been studied. The synthesis, structure, and reactivity of the extremely reactive yttrium metallocene ethyl complex Cp*2Y(CH2CH3), including activation of methane, have been reported. Significant progress has also been made in the field of endohedral metallofullerenes. Notably, encapsulation of a large La2C2 cluster inside D5(450)C100 induced a 5% axial compression of the cage, as compared with the structure of La2@D5(450)C100. The number of well-characterized heterometallic organolanthanide complexes has also witnessed a remarkable growth. An impressive number of interesting contributions have been published in the field of organolanthanide catalysis, with an emphasis on Ln-catalyzed olefin and diene polymerization. Approximately 20% of the papers published in 2015 were in the area of organoactinide chemistry. Notable results include the synthesis and characterization of homoleptic uranium(IV) tetrabenzyl complexes and a simple mono(imido) thorium complex and the first bis(imido) thorium complex, K[Th(NDipp))(NR2)3] and K2[Th(NDipp)2)(NR2)2] (Dipp=2,6-diisopropylphenyl, R=SiMe3). The reactivity of the unusual base-free imido complex [eta5-1,2,4-(Me3C)3C5H2]2ThN(p-tolyl) has also been studied. A highly remarkable achievement in 2015 was the synthesis of crystalline molecular complexes of the [{C5H3(SiMe3)2}3Th]- anion containing thorium in the formal +2 oxidation state. Various unusual transformations have been achieved using the Cp*2Th platform. For example, a unique thorium phosphinidene complex obtained from the reaction of Cp*2Th(CH3)2 with H2P(2,4,6-iPr3C6H2) has been prepared and structurally characterized. Other remarkable results include the preparation of novel actinide metallacyclocumulenes and metallacyclopentadienes. The synthesis of [3]thoro- and [3]uranocenophanes, the first structurally authenticated ansa-bridged actinocenes, has also been reported. Finally, significant progress has been made in the field of organoactinide catalysis.
