Abstract

New boron icosahedral ethers and esters formed from Cs2[closo-B12(OH)12],; Cs[closo-1-H-1-CB11(OH)11]; and closo-1,12-H2-1,12-C2B10(OH)10 are disclosed. Also set forth are their preparation by reacting the icosahedral boranes [closo-B12H12]2−, [closo-1-CB11H12]− and closo-1,12-(CH2OH)2-1,12-C2B10H10 with an acid anhdride or acid chloride to form the ester or an alkylating agent to form the ether.
