Improved synthetic route to n-B18H22.
Simple iodine oxidation of the B(9)H(12)(-) anion in toluene at room temperature reliably gives excellent yields ( approximately 80%) of n-B(18)H(22) (anti-B(18)H(22)) and thus provides a convenient, large-scale, safe route to this important polyborane cluster.
