In recent years, main group metals have emerged as viable alternatives to more traditional transition metals for a range of applications in organic chemistry, for instance as homogeneous catalysts in a variety of metal-mediated transformations or for site-selective functionalisations.
Our group has been involved for 15 years in the design of highly reactive, electron-deficient complexes based on main group metals that have often been overlooked, e.g. the large alkaline earths (Ca, Sr and Ba), tetrels (Sn, Pb) and pnictogens (Sb, Bi). In this lecture, the synthesis and bonding features of a suite of highly electrophilic complexes built around these elements will be detailed. Their implementation as molecular catalysts for E–H/E’–H heterodehydrocoupling reactions (E, E’ = Si, N, P, O) and for unusual C–H activation processes will be discussed.
