Concertedness in organic reactions (B01)

• Subject Area: Organic Molecular Chemistry - Synthesis and Characterisation
• Term: from 2007 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 27112786

Up to now, the nucleophilicity (N) and electrophilicity parameters (E), that were determined in our labs, were applied for reactions in which only one new bond is formed in the rate-determining step. The portfolio of applications for N and E will now be expanded to more complex reactions under the guiding principle of concertedness (coupling of "primitive changes"). The intended studies will comprise the change from stepwise to concerted cycloadditions and ene reactions, the transition from SN1 to SN2 reactions as well as the change from polar (concerted movement of electrons and nuclei) to SET processes, in which the electrons move faster than the nuclei.
