Abstract

9-BBN is an important compound in the synthesis of terminal alcohols by providing high regioselectivity for the anti-Markovnikov position. It is also used as a reducing agent for ketones and aldehydes and various alkyl ligation reactions. The processes involved in its synthesis and 9-BBN’s relative low solubility in most solvents renders it expensive and difficult to transport. We have made 2-isopropyl-5-methyl-7-borabicyclo[2.2.1]heptane (7-BBH) from relatively inexpensive precursor γ-terpinene and borane dimethyl sulfide complex. Characterization data and preliminary results from the use of 7-BBH for hydroboration and reduction will be discussed.
