The alkylhaloboranes are versatile intermediates which can be utilized for the preparation of many organoboron compounds containing one, two, or three boron-carbon bonds. The halides are very reactive and readily undergo reactions in which the halogen is replaced without affecting the boron-carbon bonds. In general, synthetic routes to alkylhaloboranes require the use of metals, metal alkyls, or Grignard reagentsa2 It was the purpose of this ...
