The boron halides form a number of coordination compounds with various amines, the variety of such compounds decreasing from the trifluoride to the triiodide and from the tertiary amines to the primary.1,2 Preparation is usually effected by direct combination of boron halide and amine,3- often with provision for external cooling to remove heat released in the reaction. The following syntheses exemplify general methods that can be employed. 

A review of the chemistry of Group III complexes shows that many of the concepts of Werner s coordination chemistry may be applied to these elements. Furthermore, the differences observed in the complexing behavior between ammonia and trimethylamine refiect fundamental differences in the amines. Ammonia tends to give ionic compounds, whereas trimethylamine tends to give non-ionic products. Trends observed with the metal halides can be extrapolated into hydrides of boron, aluminum, and gallium. An extension of Werner s concepts provides a significant...
