Laboratory of Organofluorine Compounds

History of the lab

Надпись: The Head of the Laboratory of Organofluorine Compounds Professor Bagrat A. Shainyan.

The Head of the Laboratory of Organofluorine Compounds Professor Bagrat A. Shainyan.

In 1994, immediately after Boris Trofimov was elected as a new Director of the Institute, the laboratory of asymmetric reactions was founded, headed Prof. B. Shainyan, for developing research in the field of optically active compounds. Since 1996, the group of Dr. S. Kirpichenko from the laboratory of organoelement compounds joined the lab. Several years in the making the laboratory continued previous studies of nucleophilic vinylic substituion and synthesis of silathiacycloalkanes developing the work on enantioselective catalytic hydrogenation. With time, more and more attention was focused on the chemistry of triflates (derivatives of trifluoromethanesulfonic acid) due to collaboration with Angarsk Electrolysis and Chemical Complex, and in 2000 the laboratory was renamed to the Laboratory of Organofluorine Compounds.

Fields of Research

The interests of the Laboratory are focused on research in the following areas:

1. Chemistry of triflates, mainly the derivatives of trifluoromethanesulfonamide with the main accent on the synthesis of new compounds and investigation of their structure and reactivity.

2. Chemistry of organosilicon compounds. These studies are mainly concentrated on silaheterocyclohexanes — synthesis of new derivatives, investigation of the structure and conformational behavior in comparison with organic analogs, and polyfunctional nitrogen-containing organosilicon compounds — synthesis, structure, reactivity, Si←O, Si←N pentacoordination.

3. Investigation of intra- and intermolecular interactions in polyfunctional compounds using the methods of molecular spectroscopy and quantum chemistry. These studies are performed on the compounds synthesized both in our lab and in many other laboratories of the Institute.

4. IR and UV spectroscopy service for the Institute.

Principal Results

The Laboratory became one of world’s leading centers in the chemistry of triflamide.

· For the first time the two- and three component reactions of condensation of triflamide with formamide and amides and sulfonamides are realized resulting in various linear and heterocyclic derivatives.

· The earlier unknown reactions of oxidative triflamidation of various alkenes, linear and cyclic dienes are investigated and the structure of the formed linear, mono- and bicyclic bridge and fused heterocycles is established.

· First unsaturated derivatives of triflamide containing double, triple and cumulated double С=С bonds are synthesized.

· The results of our own and literature studies are summarized in the first in the world’s literature comprehensive review in Chemical Reviews (2013), covering structure, reactivity, functional derivatives, salts and ionic liquids, biological activity.

The Laboratory firmly occupies one of the leading positions in the field of synthesis and conformational analysis of silaheterocyclohexanes.

· A large series of silaheterocyclohexanes with nitrogen, oxygen and sulfur heteroatoms in various positions in the ring, and various substituents at the silicon atom is synthesized, including Si-chiral and Si-functional, со связями Si—H, Si—F, Si—Ph, Si—OR.

· Within the framework of interdisciplinary and international cooperation, using the methods of low-temperature NMR spectroscopy, gas-phase electron diffraction and high-level theoretical calculations the conformational analysis of silaheterocyclohexanes was performed and principal difference of their conformational behavior from that of their organic analogs was demonstrated.

The Laboratory is actively developing the studies of organosilicon amines and their analogs.

· The mutual influence of heteroatoms in the geminal motif N—C—Si of N-(silylmethyl)amines is shown to result in an enhancement of the reactivity of the amine and silyl groups as compared to organic amines and silanes.

· General methodologies for the synthesis of 1-organyl-2-azasilatran-3-ones, N-(silylmethyl)carbamates, carboxamides and phosphoramides were elaborated.

The publication activity of the Laboratory is stably high, both quantitatively and qualitatively. In the last 3 years (2011–2013) 70 publications were issued, including 55 papers (30 in foreign journals), 4 reviews (3 in foreign journals) and theses of 11 presentations on the International and Russian conferences.
