Welcome to the latest 欧美AV Desktop Seminars, sponsored by Chemical Science, ChemComm and Chem Soc Rev. Each session will highlight two speakers, one journal board member and an early career researcher who has published in the journal.
Join Doug Stephan, Professor of Chemistry at University of Toronto and Editorial Board Chair of Chemical Communications, and Viktoria Gessner, Professor of Inorganic Chemistry at Rhur-Universit盲t Bochum, to hear about their latest work.
This 90-minute seminar will allow researchers of all professional levels to connect and share ideas and ask questions.
鈥淔LP Chemistry: A metal-free approach to the activation of strong bonds鈥�
We have previously exploited Frustrated Lewis pair (FLP) chemistry for the activation of H2, hydrogenation catalysis and the capture of small molecules. More recently we have uncovered evidence of both heterolytic and homolytic reactions for select FLPs affording either ionic or radical reaction pathways. More recent efforts to expand applications of this concept have focused on the activation of strong bonds. We are interested in the possibilities of FLP activation of the triple bonds in N2 and CO. surrogates. Herein we will discuss these efforts. While we have probed the reactions of N2 surrogates, we have also employed the concept of FLPs to activation CO for C-C bond formation. In addition, we have shown that such oligomerization of carbon monoxide in the presence 鈥渟yn-gas鈥� demonstrates the potential of FLPs in metal-free Fischer-Tropsch reactivity.

鈥淧hosphorus-Ylides: Powerful Ligands for the Stabilisation of Reactive Main Group Compounds鈥�
Reactive main group compounds such as low-valent or cationic species have received intense research interest in the past years due to their unique structures and reactivities, above all their propensity to act as transition metal mimics. The isolation of these compounds requires a careful molecular design which usually involves the use of sterically demanding and electronically stabilizing substituents. Especially, amino substituents are privileged ligands which provide thermodynamic stability due to their propensity to function as strong 蟺-donor ligands. Thus, they are often applied in low-valent species (such as carbenes) or cationic main group compounds.
