Reaktionen der Natrium-Komplexe aromatischer Ether mit Dichlor(diorganylamino)boranen/Reactions of Sodium Complexes of Aromatic Ethers with Dichloro(diorganylamino)boranes

Abstract

Abstract The reaction of anisole with Na/K-alloy and subsequent reaction with dichloro(diisopropyl-amino)borane yields diisopropylamino(diphenoxy)borane (1). In reacting the sodium complex of 1-or 2-m ethoxynaphthalene, respectively, with dichloro(diorganylamino)boranes the ether bond is cleaved. One obtains the methoxy-2-naphthoxy-diorganylam inoboranes (2a -d) besides the di-2-naphthoxy-diorganylam inoboranes (3a-e), the 2-naphthoxy-bis(diorganylamino)boranes (4a-b) and the solvated sodium-2-naphtholate (6). By-products are 1,2-bis[(diisopropylamino)-1- or 2-naphthoxyboryl]ethyne derivatives 5a and 5b, terized analytically and spectroscopically (MS; NMR: 1H, 11B, 13C).
