1,2-Dicarba-closo-dodecaboran-1-yl naphthalene derivatives

1,2-Dicarba-closo-dodecaboranes (o-carboranes) and naphthalenes have potential value as components or building blocks for supramolecular systems. We have efficiently synthesized 1-(1,2-dicarba-closo-dodecaboran-1-yl)naphthalene and 2-(1,2-dicarba-closo-do

C-arylation and C-heteroarylation of icosahedral carboranes via their copper(I) derivatives

Reaction between C-mono- or C,C'-di-copper(I) derivatives of 1,2- 1,7-, or 1,12-dicarba-closo-dodecaborane(12) and aryl iodides in the presence of pyridine gives the corresponding C-mono- or C,C'-diaryl derivatives of 1,7- and 1,12-dicarba-closo-dodecaboranes(12); 1,2-dicarba-closo-dodecaborane(12) gives only the C-monoaryl product.Cyclic or linear arylene coupled systems are obtained when di-iodoarenes are used.Copper(I) derivatives may be generated from C-unsubstituted or C-monosubstituted carboranes using copper(I) t-butoxide when substituents incompatible with the use of C-lithio-intermediates are involved.The C-copper(I) derivative of 1,2-dicarba-closo-dodecaborane(12) gives 1,2-di-2'-pyridyl-1,2-dicarba-closo-dodecaborane(12) specifically with 2-bromopyridine.The (inferred) intermediate mono-2-pyridyl-derivative, obtained independently from 2-ethynylpyridine and the dimethylsulphide complex of decaborane, gives 1-phenyl-2,2'-pyridyl-1,2-dicarba-closo-dodecaborane(12) upon conversion into its copper(I) derivative and treatment with iododobenzene.However, the copper(I) derivative of 1-phenyl-1,2-dicarba-closo-dodecaborane(12) does not react to a significant extent with 2-bromopyridine.
