Abstract

Sodium salts of the spiroborate anion bis[(1,1′-binaphthalene)-2,2′-diolato-O,O’]borate in enantiopure and racemic forms have been obtained through reaction of BORAX (sodium tetraborate hexahydrate) with the corresponding stereoisomers of BINOL [(1,1′-binaphthalene)-2,2′-diol]. Electrocrystallisation of these salts with BEDT-TTF produces single crystals of a 1:1 radical-cation salt, (BEDT-TTF){B[1,1′-bis(BINOL)]₂}•THF, with the racemic spiroborate anion whilst no crystals were obtained with the enantiopure forms.

手性和外消旋 BINOL 螺硼酸阴离子和 BEDT-TTF 自由基阳离子盐

通过 BORAX（六水合四硼酸钠）与 BINOL [(1,1′-联萘)-2,2′-二醇] 的相应立体异构体反应，获得了对映体和外消旋体形式的螺硼酸阴离子双[(1,1′-联萘)-2,2′-二醇-O,O']硼酸钠盐。用 BEDT-TTF 对这些盐进行电结晶，可得到带有外消旋螺硼酸阴离子的 1:1 自由基阳离子盐 (BEDT-TTF){B[1,1′-bis(BINOL)]2}-THF 单晶，而对映体则没有晶体。

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
