Abstract

and Economics, in 1996, and he was the head of this Department in the period of 1999-2006. After a fusion in 2007, he has been the head of the Department of Organic Chemistry and Technology. His research interests include organophosphorus and environmentally friendly chemistry comprising P-heterocycles, low-coordinated P-fragments, P(III)-ligands, their borane-and transition metal complexes, catalytic reactions, selective syntheses, resolution of P(IV) compounds, microwave synthesis, ionic liquids, and optimization of reactions by on-line methods.

Organophosphorus‐Selenium Heteroatom Derivatives from Selenation of Primary/Secondary Amines and Haloalkanes/Dihaloalkanes

“…These new heteroatom compounds were isolated in good to excellent yields (41% -93%) ( Table 1) as sticky oils or pastes which are soluble in both chlorinated solvents and tetrahydrofuran. It should be noted that products 2e-l bearing the strong electron-withdrawing group R 3 (R 3 = p-BrC 6 H 4 COCH 2 ) were obtained in rather high yields (55% -93%), meanwhile, products 2b and 2c bearing less electron-withdrawing group R 3 (R 3 = CH 3 (CH 2 ) 10 or CH 3 (CH 2 ) 6 ) were isolated in the lowest yields (41% and 42%). Thus, it appears that a strong electronwithdrawing group R 3 is hugely beneficial for the formation of the reaction products.…”

“…[1][2][3] A wide range of applications have been documented in different fields such as coordination chemistry, material science, homogeneous catalysis, development of biologically active compounds or pesticides, and additives for polymers such as lubricants and antioxidants. [4][5][6][7][8][9][10] 2,4-Bis(phenyl)-1,3-diselenadiphosphethane-2,4-diselenide [{PhP(Se)(µ-Se)} 2 ] (Woollins' reagent, WR), a selenium counterpart of the wellknown Lawesson's reagent (LR), has been well developed as an efficient phosphorus-selenium containing building block or selenation reagent in organic synthetic chemistry in recent years. 11 The reactions of WR with various organic substrates exhibit a diverse spectrum ranging from simple oxygen-selenium exchange to the formation of complex phosphorus-selenium heterocycles as well as the formation of surprising phosphorus-selenium-free products.…”

Environmentally Friendly Chemistry with Organophosphorus Syntheses in Focus

“…In the last years, the synthesis and catalytic activity of a variety of transition metal complexes incorporating mono-or bidentate 5-, 6-or 7-membered P-heterocyles were described [77]. Our research group also studied the synthesis of the platinum complexes with P-heterocyclic and bisphosphine ligands [78,79].…”

A study on the optical resolution of 1-isopropyl-3-methyl-3-phospholene 1-oxide and its use in the synthesis of borane and platinum complexes

“…The P-heterocyclic derivatives form a special group [3]. However, there are only a few examples in the literature for P-heterocyclic phosphines bearing an asymmetric phosphorus atom [4][5][6].…”
