  • Catalytic, Thermal, Regioselective Functionalization of Alkanes and Arenes with Borane Reagents
    ACS Symposium Series 885, Activation and Functionalization of C-H Bonds, Karen I. Goldberg and Alan S. Goldman, eds. 2004. CHAP TER 8 Catalytic, Thermal, Regioselective Functionalization of Alkanes and Arenes with Borane Reagents John F. Hartwig Department of Chemistry, Yale University, New Haven, Connecticut 06520-8107 Work in the author’s group that has led to a regioselective catalytic borylation of alkanes at the terminal position is summarized. Early findings on the photochemical, stoichiometric functionalization of arenes and alkanes and the successful extension of this work to a catalytic functionalization of alkanes under photochemical conditions is presented first. The discovery of complexes that catalyze the functionalization of alkanes to terminal alkylboronate esters is then presented, along with mechanistic studies on these system and computational work on the stoichiometric reactions of isolated metal-boryl compounds with alkanes. Parallel results on the development of catalysts and a mechanistic understanding of the borylation of arenes under mild conditions to form arylboronate esters are also presented. © 2004 American Chemical Society 136 137 1. Introduction Although alkanes are considered among the least reactive organic molecules, alkanes do react with simple elemental reagents such as halogens and oxygen.1,2) Thus, the conversion of alkanes to functionalized molecules at low temperatures with control of selectivity and at low temperatures is a focus for development of catalytic processes.(3) In particular the conversion of an alkane to a product with a functional group at the terminal position has been a longstanding goal (eq. 1). Terminal alcohols such as n-butanol and terminal amines, such as hexamethylene diamine, are major commodity chemicals(4) that are produced from reactants several steps downstream from alkane feedstocks.

Box 12065, The Hebrew University of Jerusalem, Jerusalem 91120, Israel 2Novosibirsk Institute of Organic Chemistry SB RAS, 9, Lavrentieva Ave., Novosibirsk, 630090, Russia Abstract Problems on using of β-aminoalkyl- and β-sulfanylalkylboranes in organic synthesis are considered in this review. The synthesis of boron containing α-aminoacids by Curtius rearrangement draws attention. The use of β-aminoalkylboranes available by enamine hydroboration are described. Examples of enamine desamination with the formation of alkenes, aminoalcohols and their transfor- mations into allylic alcohol are presented. These conversions have been carried out on steroids and nitro- gen containing heterocyclic compounds. The dihydroboration of N-vinyl-carbamate and N-vinyl-urea have been described. Examples using nitrogen and oxygen containing boron derivatives for introduction of boron functions were presented. The route to borylhydrazones by hydroboration of enehydrazones was envisaged. The possibility of trialkylamine hydroboration was shown on indole alkaloids and 11-azatricyclo- [6.2.11,802,7]2,4,6,9-undecatetraene examples.

Firstly, HPPANI was prepared via self-stabilization dispersion polymerization method in a heterogeneous reaction medium. Second step involves doping of emeraldine base form of HPPANI with boron trifluoride under reduced vacuum. The resultants BF3 doped HPPANI have been well characterized by using UV- Visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetry. The spectroscopic data indicated that the interaction between HPPANI and BF3.Thermogravimetry studies revealed that the BF3 doping improved the thermal stability of defects free PANI. Keywords: Conducting polymers; High performance PANI; Doping; Boron trifluoride; Thermal stability. Introduction Conducting polymers have attracted increasing attention because they offers the possibility of generation of novel materials with diverse applications for electromagnetic interference (EMI) shielding, rechargeable battery, chemical sensor, organic light emitting devices, corrosion devices, and microwave absorption1–5. Among conducting polymers, polyaniline (PANI) is the promising electrical conducting polymer due to its a broad range of tunable properties derived from its structural flexibility, good environmental stability, easy preparation in aqueous solution, and organic solvents, optical, electrical properties and unique redox chemistry6-7.
