Aminoiminoborane als Synthone zum Aufbau drei‐ und viergliedriger Ringe mit der Ringatomsequenz BNE, BNBE, BNSiE und NBNE (E = P, z. T. auch B, Si, Ge, As)

Abstract: 'P(NiPr3 (9, warend sich rnit Li2EPh (E = P, As) aus 2a, c Vier- with A = B(NiPr2) (3), SiR2 (4a, b), P(NiPr)2 (5), whereas the dechlorination of 24, c with Li2EPh (E = P, As) yields the four-membered ring products [-B(NiPr2)"(tBu)-A-Ei(Ph)-]with A = B(NiPrz) (6, 7), SiMe2 (8, 9). Dichiorides AC12 are added to the iminoborane Me,Si(tBu)N-B=NtBu Chem.

“…[11] Although derivatives of (B 3 H 3 ) 2À have not yet been synthesized, related isoelectronic ring compounds such as monoanionic molecules in which one of the ring boron atoms is replaced by carbon (diboriranides) have been reported (Scheme 3a). [12,13] Protonation of the ring compound shown in Scheme 3a occurs at the B À Bb ond rather than the Catom, thereby leading to a( 3c,2e) B À H À B bridge.M oreover,t he chemistry of azadiboriridines,e specially tri-tert-butylazadiboriridine (Scheme 3b), [14,15] has been intensively studied by Paetzold et al and other research groups.

“…Protonation of the ring compound shown in Scheme a occurs at the B−B bond rather than the C atom, thereby leading to a (3c,2e) B−H−B bridge. Moreover, the chemistry of azadiboriridines, especially tri‐ tert ‐butylazadiboriridine (Scheme b), has been intensively studied by Paetzold et al. and other research groups .…”

“…Mehrere der in der Folge diskutierten Elektronen‐defizitären B 4 ‐Ringverbindungen können formal, entweder durch Oxidation oder durch Protonierung, abgeleitet werden von der Verbindung mit der maximalen Elektronenzahl (10 GE), (B 4 H 4 ) 2− (dabei werden Bor‐haltige Heterozyklen, wie Diazadiboretidine mit zwölf Elektronen, nicht berücksichtigt). Daher beginnt die Diskussion in diesem Abschnitt mit diesem Molekül.…”

“…Protonierung der in Schema a gezeigten Ringverbindung findet an der B‐B‐Bindung und nicht am C‐Atom statt und führt zu einer (3c,2e)‐B‐H‐B‐Brücke. Ferner wurde die Chemie der Azadiboriridine, speziell des Tri‐ tert ‐butylazadiboriridins (Schema b) intensiv von Paetzold et al. und anderen Gruppen untersucht .…”
