Quantitative syntheses of permethylated closo-1,10-R(2)C(2)B(8)Me(8) (R = H, Me) carboranes. Egg-shaped hydrocarbons on the Frontier between inorganic and organic chemistry

Electrophilic methylation of the closo-1,10-R(2)C(2)B(8)H(8) (1) (R = H or Me) dicarbaboranes at higher temperatures or thermal rearrangement of the 1,6-R(2)C(2)B(8)Me(8) (3) compounds at 400–500 °C generated the B-permethylated derivatives closo-1,10-R(2)C(2)B(8)Me(8) (2) in quantitative (>95%)...

Descripción
Sumario:Electrophilic methylation of the closo-1,10-R(2)C(2)B(8)H(8) (1) (R = H or Me) dicarbaboranes at higher temperatures or thermal rearrangement of the 1,6-R(2)C(2)B(8)Me(8) (3) compounds at 400–500 °C generated the B-permethylated derivatives closo-1,10-R(2)C(2)B(8)Me(8) (2) in quantitative (>95%) yields. The compounds exhibit extreme air stability as a consequence of a rigid, egg shaped hydrocarbon structures incorporating inner 1,10-C(2)B(8) carborane core.
