New 1 : 1 adducts of BBr3 and BI3 with (CH3)3As and (CH3)3Sb are reported. The (CH3)3As adducts are stable indefinitely at room temperature under an inert atmosphere while the (CH3)3Sb compounds slowly decompose at that temperature to form (CH3)3SbX2 (X = Br, I). Boron-11 and proton NMR data suggest that these species may exist as ions in chloroform solution.
据报道BBr 3和BI 3与(CH 3)3 As和(CH 3)3 Sb的新的1:1加合物。(CH 3)3 As加合物在惰性气氛下于室温下无限稳定,而(CH 3)3 Sb化合物在该温度下缓慢分解形成(CH 3)3 Sb X 2(X = Br,I)。
硼11和质子NMR数据表明,这些物质可能以离子形式存在于
氯仿溶液中。
