Our New Approach
Our group is especially interested in
- EN (E = element of group 15)
chemistry with the focus on binary cyclic and acyclic species which can be either ions (cations or anions) or neutral systems. To achieve this goal we have developed a new [3+2] cycloaddition reaction which utilizes disguised 1,3 dipoles and/or dipolarophiles. Hence prior to the cyclization one or more eliminations steps are necessary. Moreover, our research is focussed on small molecule activation by utilizing four-membered E2N2 biradicaloids developed in our group.
Kinetic Protection - Bulky Groups
Since binary EN compounds are mostly thermodynamically unstable species, kinetic protection is needed to stabilize binary EN compounds. Here we use well-estabilished bulky groups such as the terphenyl, supermesityl or hypersilyl group.
Stabilization of Strong Electrophiles - Weakly Coordinating Cations/Anions
In case of binary EN ions, the counterion must fullfil two criterions:
- It must be chemically inert.
- It should be weakly coordinating.
