From anionic N-heterocyclic dicarbenes to abnormal carbene-borane complexes: A logical synthetic route
Wang, Yuzhong,Abraham, Mariham Y.,Gilliard, Robert J.,Wei, Pingrong,Smith, Jared C.,Robinson, Gregory H.
, p. 791 - 793 (2012)
The anionic N-heterocyclic dicarbenes (NHDCs) I are demonstrated to be a convenient platform from which abnormal NHC (aNHC)-borane complexes V-VII may be prepared. The anionic NHDC binuclear complex II and the aNHC mononuclear adduct VII can be interconverted through lithiation and protonation, respectively, of the C2 carbon atom of the imidazole ring.

Ono, Shintaro,Watanabe, Takashi,Nakamura, Yosuke,Sato, Hiroyasu,Hashimoto, Toru,Yamaguchi, Yoshitaka

The reaction of N-heterocyclic carbene (NHC) complexes of silver with BH3 or BEt3 was investigated. On treatment of IiPr·AgCl (1-AgCl) (IiPr = 1,3-diisopropylimidazol-2-ylidene) with two equivalents of NaBH
The parent borylene: Betwixt and between
Curran, Dennis P.,Boussonniere, Anne,Geib, Steven J.,Lacote, Emmanuel
, p. 1602 - 1605 (2012/05/05)
Still elusive: The reduction of dimethylimidazol-2-ylidene dichloroborane by sodium naphthalenide has been suggested to provide a borylene that cycloadds to naphthalene to make a borirane. Evidence has been provided that this borirane instead arises from
A dialkylborenium ion via reaction of N-heterocyclic carbene-organoboranes with Bronsted acids - Synthesis and DOSY NMR studies
McArthur, David,Butts, Craig P.,Lindsay, David M.
, p. 6650 - 6652 (2011/07/08)
A dialkylborenium ion stabilized by an N-heterocyclic carbene has been prepared for the first time by reaction of IMes·9-BBN-H with triflic acid. The ion-separated nature of the borenium ion was confirmed by 1H and 19F diffusion ordered NMR spectroscopy.
Iridium-mediated borylation of benzylic C-H bonds by borohydride
Tang, Christina Y.,Smith, William,Thompson, Amber L.,Vidovic, Dragoslav,Aldridge, Simon
, p. 1359 - 1362 (2011/04/22)
Simple source: An intramolecular iridium-mediated C-H borylation proceeds through transfer of a BH3 fragment from borohydride to a benzylic carbon center (see scheme; coe=cyclooctene). Simple and inexpensive LiBH 4 is thus utilized as the boron source in C-H to C-B conversion.
The synthesis of chiral N-heterocyclic carbene-borane and -diorganoborane complexes and their use in the asymmetric reduction of ketones
Lindsay, David M.,McArthur, David
, p. 2474 - 2476 (2010/08/06)
Chiral N-heterocyclic carbene-borane complexes have been synthesised, and have been shown to reduce ketones with Lewis acid promotion. Chiral N-heterocyclic carbene-borane and -diorganoborane complexes can reduce ketones with enantioselectivities up to 75
Synthesis and reactivity of triethylborane adduct of N-heterocyclic carbene: Versatile synthons for synthesis of N-heterocyclic carbene complexes
Yamaguchi, Yoshitaka,Kashiwabara, Taigo,Ogata, Kenichi,Miura, Yumiko,Nakamura, Yoshiyuki,Kobayashi, Kimiko,Ito, Takashi
, p. 2160 - 2161 (2007/10/03)
The reaction of an imidazolium salt with LiBEt3H afforded triethylborane adduct of imidazol-2-ylidene, which can act as a carbene precursor for the synthesis of a transition metal complex as well as a main group element complex.
