	Article:	NEW DIORGANOCHALCOGEN COMPOUNDS BASED ON THE 2-(ME₂NCH₂)C₆H₄ GROUP. Authors: BIANCA DANCIU, ROXANA POPA, ALEXANDRA POP, VALENTIN ZAHARIA, CRISTIAN SILVESTRU, ANCA SILVESTRU.


	Abstract: Heteroleptic diorganochalcogen compounds of type R[2-(Me₂NCH₂)C₆H₄]E [R = (phtz)CH₂, E = Se (1), S (2); R = (4-Cl-phtz)CH2, E = S (3); R = (pz)CH₂CH₂, E = Se (4)] were prepared by reacting 2-(Me₂NCH₂)C₆H₄ELi with the appropriate organic halide in a 1:1 molar ratio. The new compounds were investigated in solution by ¹H, ¹³C and ⁷⁷Se NMR where appropriate. For compounds 1 and 4 the crystal and molecular structures were determined by single-crystal X-ray diffraction. Keywords: Diorganoselenium compounds, hypercoordination, structure elucidation
