Reaction of Metal and Metalloid Compounds with Polyfunctional Molecules. XLI. Synthesis of 9-Bora-10-oxa-phenanthrenes, Bis(2′-oxy-terphenylyl)halogenoboranes, and Bis(9-bora-10-oxa-phenanthrenyl)oxidesThe reaction of 2′-hydroxy-m-terphenyl and 2-hydroxy-biphenyl resp. with n-C4H9Li and Na resp. and subsequent addition of trihalogenoboranes yields 9-halogeno-9-bora-10-oxa-phenanthrenes 1, 2, 5 and A besides 9-2′-oxy-m-terphenylyl-9-bora-10-oxa-phenanthrene 3 and bis-(9-bora-10-oxa-phenanthrenyl)oxides 4 and 6. Under somewhat different reaction conditions one obtains also the bis(2′-oxy-terphenylyl)halogenoboranes 7 and 8, tris(2-oxy-biphenylyl)-borane 9 and t-butyl-chloro-(2-oxy-biphenylyl)borane 10. 11 results from reaction of 2 with lithated hexamethyldisilazane. The compounds are characterized analytically and spectroscopically (1H, 11B-nmr spectra; mass spectra). For 4 and 6 X-ray analyses were performed.
Notes:
Die Reaktion von lithiiertem bzw. natriiertem 2′-Hydroxy-m-terphenyl bzw. 2-Hydroxy-biphenyl mit Trihalogenboranen ergibt neben den 9-Halogeno-9-bora-10-oxaphenanthrenen 1, 2, 5 und A, 9-2′-Oxy-m-terphenylyl-9-bora-10-oxa-phenanthren 3, die Bis(9-bora-10-oxa-phenanthrenyl)oxide 4 und 6. Durch etwas veränderte Reaktionsbedingungen sind auch die Bis(2′-oxy-terphenylyl)-halogenoborane 7 und 8, Tris(2-oxy-biphenylyl)boran 9 und t-Butyl-chloro-(2-oxy-biphenylyl)boran 10 erhältlich. 11 erhält man durch Reaktion von 2 mit lithiiertem Hexamethyldisilazan. Die Verbindungen werden analytisch und spektroskopisch (1H, 11B-NMR; MS) charakterisiert. Von 4 und 6 wurden Röntgenstrukturen angefertigt.
