Abstract

Abstract Novel borates (ArBMe 3) Li· OEt 2 (I),(ArBEt 3) Li· OEt 2 (II) and (BArPh-9-BBN) Li· OEt 2 (III)(Ar C 6 H 4 CH 2 NMe 2-2, 9-BBN= 9-borabicyclo [3.3. 1] nonyl) were synthesized in the reactions of ArLi with BMe 3, BEt 3 and BPh-9-BBN, respectively. Detailed studies were made of 1 H, 13 C, 11 B NMR, IR and molecular weight measurements. For I, II and III an alkyl and/or aryl bridged structure is proposed. The following order of stability of the ...
