Prof. Risto Laitinen
Laboratory of Inorganic Chemistry, University of Oulu, Finland

Risto Laitinen received his Ph.D. in 1982 in Helsinki University of Technology (Finland). He joined University of Oulu (Finland) in 1988, first as Associate Professor of Inorganic and Analytical Chemistry, and since 1993 as Professor of Inorganic and Analytical Chemistry. He has served as Head of Chemistry Department in 1993-1999, 2003-2008, and 2010-2013. In 1984-1985 he was an Alexander von Humbold research fellow in Technische Universität Berlin (Germany). His research interests lie in synthetic, structural, and computational chemistry of sulfur, selenium, and tellurium. He has collaborated extensively with several research groups in different Canadian universities and is a constant visitor in Canada. He has long been involved in IUPAC (Member of Union Advisory Board 2004-2005, secretary, member, and national representative of Commission on Nomenclature of Inorganic Chemistry 1981-2001, and a titular member and secretary in Division of Chemical Nomenclature and Structure Representation 2015-).

	Program The full program and summary of the program are available for donwload. Only a summary of the program will be printed and available at the conference. If you need, please print your own complete copy or have it as a pdf file on your electronic device. We will provide lunch on Saturday, Nov. 12. Social Events Mixer Friday, November 11, 7:00-10:00 pm Location: The Gown & Gavel pub in the Hamilton downtown. 24 Hess St. South, Hamilton, ON L8P 3M8. Map Banquet Saturday, November 12, 7:30-10:00 pm Location: The Dundas Valley Golf and Curling Club. 10 Woodleys Ln, Dundas, ON L9H 6Y6. Map There will be two busses (90 passengers in total) taking the participants from McMaster University to the banquet. The pick-up location is shown on the McMaster map, and it will be north of the MDCL building. At 7:15 pm, the busses will depart from McMaster to the Dundas Valley Golf Club. At 10:15 pm, the busses will take the participants from the Dundas Valley Golf Club to the Hamilton downtown. The stop will be on the Bay St. South, close to the Homewood Suites by Hilton. By car: From the parking lot, go back to the University Avenue by looping around the hospital. Turn right onto the Main Street and exit right onto the Cootes Drive. Continue straight on the Cootes Drive and then on the King Street West (also Hwy 8), which takes you through the Dundas downtown. Right after you leave Dundas and before you go under the railway bridge, take the Woodleys Ln on your left. Plenary lectures

	Formation of Sulfur and Selenium Imides via Cyclocondensation and Cyclodimerization Cyclocondensation reactions between primary amines and SCl₂ or S₂Cl₂ afford eight-membered rings, e.g. 1,3,5,7-S₄(NMe)₄,or the six-membered rings 1,4-S₄(NR)_2, respectively. By contrast, a complicated mixture of products is formed upon cyclocondensation of ^tBuNH₂ with SeCl₂. A variety of cyclic selenium imides with the ring sizes 6-8 and 15, as well as the acyclic imido selenium dichlorides ClSe[N(^tBu)Se]_nCl (n = 1-3), have been isolated from these mixtures and identified by a combination of ⁷⁷Se NMR spectroscopy and single crystal XRD. The product distribution is dependent on the molar ratio and the concentration of the reagents. ClSe[N(^tBu)Se]₂Cl has been found to be a bifunctional reagent and concurrently affords 1,3-Se₃(N^tBu)₂ and 1,3,5-Se₃(N^tBu)₃ upon treatment with ^tBuNH₂in THF. Cyclic selenium imides are generated from this acyclic precursor either by reduction or by nucleophilic substitution. The imidoselenium dichlorides are likely intermediates in the formation of the cyclic selenium imides from ^tBuNH₂ and SeCl₂. The [2+2] cyclodimerization of chalcogen diimides E(NR)₂ (E = S, Se; R = alkyl, aryl) to form the dimers RNE(μ-NR)₂ENR is endergonic for sulfur diimides, approximately energy-neutral for selenium diimides, and spontaneous for tellurium diimides. Although the monomeric structure of Se(NAd)₂ in the solid state has been established,selenium(IV) diimides undergo thermal decomposition in solution to give a mixture of cyclic selenium imides. It has recently been observed that Group 12 metal dichlorides assist the cyclodimerization of Se(N^tBu)₂. Once formed, the dimer is kinetically stable due to a relatively high energy barrier towards dissociation.

	Ligand Design in Organometallic Chemistry Taken to the Extreme: when the Metal is no Longer Needed Ligand design has been playing a very important role in the optimization of transition-metal catalyzed processes. In the past decade, our research group has been working on the synthesis and coordination chemistry of ambiphilic molecules having both a group XIII Lewis acid and a Lewis base within the same framework. Contrarily to Frustrated Lewis Pairs (FLPs) the molecules studied do not contain significant steric bulk. Along the road, we discovered that some ambiphilic molecules were more active for small molecule activation than the related coordination complexes. Indeed, as in FLP chemistry, the Lewis acid and the Lewis base can cooperate and behave similarly to a transition metal in 2-electron transfer processes, making possible some metal-free transformations that were thought to be exclusive to transition metals. By fine tuning of the steric and electronic properties of both partners in these "metal-free organometallic" species, the same way organometallic chemists design ligands for transition metals, it is possible to obtain catalytic activities that are as good, and sometime better, than traditional transition metal systems. This talk will detail the reactivity of ambiphilic molecules in the hydroboration of carbon dioxide, hydrogenation of carbon dioxide, borylation of heteroarenes6 and in dehydrogenative diboration of hydroboranes.
