Thiocyanation of BODIPY dyes and their conversion to thioalkylated derivatives

, 2015
A high-yielding method for the direct thiocyanation of BODIPY dyes is described. In 1,3-dimethyl BODIPYs, the thiocyanato group adds at position 2, whereas the insertion occurs at position 5 in 3-amino BODIPYs. The transformation of the thiocyanato group

Thiocyanation of closo-Dodecaborate B₁₂H₁₂²⁻. A Novel Synthetic Route and Theoretical Elucidation of the Reaction Mechanism

, 2016
Although vast experimental experience has been accumulated about the reactions of icosahedral B12H122− borane cages, little is known about the mechanisms by which these reactions proceed. To address this issue, we have chosen the thiocyanation of B12H122−
