Research Interests

Main Group (1A, 2A) Organometallic Chemistry.

Alkali metal radical anions and dianions as homogeneous sources of alkali metals in organometallic synthesis, including solid state synthesis.

Reagents and catalytic systems containing mixed 1A, 2A metal organics and alkoxides designed for controlling chemo- and regioselectivity in reactions such as carbon-lithium bond formation or alkylation by ethylene.

Development of novel functionalized organolithium reagents with application to the synthesis of novel phosphorus ligands for transition metal catalysis, or to the synthesis of other functional materials e.g. NLO and NIR materials.

Dendrimer chemistry.

Originator: of ''Reductive lithiation''for making carbon -lithium bonds
C.G.Screttas, J.C.S. Chem. Commun. 1972, 752 ( reductive lithiation of alkyl and aryl halides)
C.G.Screttas and M.Micha-Screttas, J.Org.Chem. 1978, 43, 1064 (reductive lithiation of alkyl phenylthioethers as well as the first report of naphthalene catalysis in this reaction).
