Contributions to the Chemistry of Boron, 209. - 1,2-Diborane(4)diyl and 1,3-Triborane(5)diyl Ditosylate and Bis(triflate): Electron-Precise Polyborane Derivatives with Active Leaving Groups

Introduction of the tosylate or triflate group into dimethylamino polyboranes gives electron-precise polyborane derivatives of high reactivity.Five representives 1-4 of these types of compounds are reported.The RSO3 group strengthen the B-N bond while they are good leaving groups as shown by alkylation reactions when using LiR compounds.The X-ray strcture of B2(NMe2)2(tos)2 (1) reveals C2 symmetry, and this also holds for B2(NMe2)2(CCPh)2 (7).While the two BNO planes in 1 include an angle of 80.8 deg, the two BNC planes in 7 are closer to orthogonality (84.6 deg).In contrast, the bis(9-fluorenyl)diborane 10 reveals different structures in solution and the solid state.Experimental results correspond fairly well with MNDO calclations on model compounds B2(NH2)2X2, particularly with B-B and B-N bond lengths and conformations.They also suggest that the nucleophilic substitutions at 1-4 may proceed by a dissociative process. Key words: Diborane(4) derivatives; triborane(5) derivatives.
