2,4,6-tri-iso-propylphenyl-, 3,5-bis(trifluoromethyl)phenyl-, and pentafluorophenyl-Grignard reagents resulted in the formation of the corresponding oxaboraphenanthrene derivatives namely 9-phenyl- (2), 9-p-tolyl- (3), 9-(3,5-dimethylphenyl)- (9-m-xylyl-) (4), 9-mesityl- (5), 9-(2,4,6-tri-iso-propylphenyl)- (6), 9-(3,5-bis(trifluoromethyl)phenyl)- (7), and 9-(pentafluorophenyl)-10,9-oxaboraphenanthrene
9-氯10,9-oxaboraphenanthrene(的反应1)与所述苯基,对-甲苯基- ,米-xylyl-,mesityl-,2,4,6-三-异-propylphenyl-,3,5-双(三氟甲基)苯基-和五氟苯基-格氏试剂导致形成相应的氧杂苯并菲衍生物,即9-苯基-(2),9-对甲苯基-(3),9-(3,5-二甲基苯基)-( 9-米-xylyl-)(4),9- mesityl-(5),9-(2,4,6-三-异丙-propylphenyl) - (6),9-(3,5-双(三氟甲基)苯基)-(7)和9-(五氟苯基)-10,9-氧杂苯并菲(8)。使用1和Li [C(SiMe 3)3 ]或Na [Si t Bu 3 ]作为反应物,有选择地获得9-Trisyl-(9)和9-supersilyl-10,9-oxaboraphenanthrene(10)。化合物4 – 9通过X射线晶体学表征。嵌入PMMA的5
