| الوصف: | The electrophilic substitution of icosahedral closo- 1-SB 11 H 11 with methyl iodide has resulted in two B-functionalized thiaboranes, 7,12-I 2 -2,3,4,5,6,8,9,10,11-(CH 3 ) 9 -1- closo -SB 11 and 7,8,12-I 3 -2,3,4,5,6,9,10,11-(CH 3 ) 8 - closo -1-SB 11 , with the former being significantly predominant. These two icosahedral thiaboranes are the first cases of polysubstituted polyhedral boron clusters with another vertex that differs from B and C. Such polyfunctionalizations have increased the earlier observed thiaborane icosahedral barrier, not exhibiting any reactivity toward bases, unlike the parent thiaborane. The search for methylation pathways has revealed that the complete B 11 -methylation is impossible, like in the case of decaborane(14), where this seems to be a result of the positively charged upper parts of these two molecules. |
