METHOD FOR COMBINED SYNTHESIS OF 2,6,8,11-TETRAETHYL-4-PHENYL-1,7-DITHIA-4-AZA-2,6,8,11-TETRAALUMINACYCLOUNDECANE AND 2,4,7,9,12-PENTAETHYL-5-PHENYL-18-DITHIA-5-AZA-2,4,7,9,12-PENTAALUMINACYCLODODECANE

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to organic chemistry, particularly to a method for combined synthesis of 2,6,8,11-tetraethyl-4-phenyl-1,7-dithia-4-aza-2,6,8,11-tetraaluminacycloundecane(1) and 2,4,7,9,12-pentaethyl-5-phenyl-1,8-dithia-5-aza-2,4,7,9,12-pentaalumina-cyclododecane (2): . Method involves reaction of 3-phenyl-1,5,3-dithiazepane with EtAlCl₂ in presence of magnesium powder with participation of catalyst Cp₂TiCl₂. Molar ratio is as follows: 3-phenyl-1,5,3-dithiazepane: EtAlCl₂ : Mg : Cp₂TiCl₂=1 : (4.5-5.5) : (4.5-5.5) : (0.03-0.07). Reaction is carried out in a mixture of solvents Et₂O-tetrahydrofuran (1:1, volume), in an argon atmosphere at 35-45 °C for 6-10 hours.;EFFECT: obtained compounds can be used in fine organic and organometallic synthesis.;1 cl, 1 tbl, 1 ex
