摘要: Novel borates (ArBMe3)Li · OEt2 (I), (ArBEt3)Li (II) and (BArPh-9- BBN)Li (III) (Ar C6H4CH2NMe2-2, 9-BBN = 9-borabicyclo[3.3.1]nonyl) were synthesized in the reactions of ArLi with BMe3, BEt3 BPh-9-BBN, respectively. Detailed studies made 1H, 13C, 11B NMR, IR molecular weight measurements. For I, II III an alkyl and/or aryl bridged structure is proposed. The following order stability bridges has been established: (BArPh-9-BBN)Li > OEt2.
