The method for synthesis of 2-sulfonium closo-decaborate anions derivatives with exo-polyhedral aminogroups

Recent Achievements on Functionalization within closo‐Decahydrodecaborate [B10H10]2− Clusters

“…[2-B 10 H 9 SH] 2À anion reacts with both acid anhydrides and carboxylic acid chlorides in presence of triethylamine to produce the acyl derivative. [44] The use of bromoalkyl phthalimides allowed the formation of derivatives of sulfonium decaborate anion with amino functional groups. The reaction of closo-decaborate with N-bromoalkyl phthalimides in DMF in the presence of cesium carbonate proceeds with a higher yield and lower reaction time.…”

“…Under mild conditions at room temperature, the alkylation of [2‐B 10 H 9 SH] 2− anion by iodoacetamide was accompanied by secondary reactions of iodination of the boron cluster. [2‐B 10 H 9 SH] 2− anion reacts with both acid anhydrides and carboxylic acid chlorides in presence of triethylamine to produce the acyl derivative [44] . The use of bromoalkyl phthalimides allowed the formation of derivatives of sulfonium decaborate anion with amino functional groups.…”

Fused 1,2-Diboraoxazoles Based on closo-Decaborate Anion–Novel Members of Diboroheterocycle Class

“…Similarly, for other closo -borate anions of general type [B n H n ] 2− (n = 6–12), the main approaches for their functionalization are based on electrophilic and nucleophilic processes. Using these methods, derivatives with exo -polyhedral B–C [ 28 , 29 , 30 ], B–N [ 31 , 32 , 33 ], B–O [ 34 , 35 , 36 ], B–S [ 37 , 38 , 39 ], and B–Hal [ 40 , 41 ] (Hal =F,Cl,Br,I) bonds have been received. Nitrilium derivatives of general type [B n H n N≡CR 2 ] − (R 2 = Me, Et, t Bu, Ph) (n = 10,12) are a very suitable molecular platform for creating molecular systems with given properties [ 42 , 43 , 44 ].…”

Synthesis of Perchlorinated Sulfonium Derivatives of closo-Decaborate Anion [2-B10Cl9SR2]− (R = i-C3H7, n-C3H7, n-C4H9, n-C8H17, n-C12H25, n-C18H37, CH2Ph, and cyclo-S(CH2)4)

“…At present, there are many different methods of complete and partial halogenation of boron clusters: carboranes, , closo -decaborate, , and closo -dodecaborate anions. , Further studies of these compounds showed that they can be used as components for ionic liquids. − In addition, similar processes for substituted derivatives of cluster anions, which are now being actively studied, − are beginning to gain popularity. According to published results, , the replacement of hydrogen atoms with halogens also significantly lowers the melting point of boron cluster anion derivatives.…”
