METHOD FOR PREPARING 2,2,7,7-TETRAMETHYL-4,9-BIS-(DIMETHYLAMINO)- TETRAHYDRO-1,6,4,9,2,7-DIOXADIAZADISILECIN-5,10(2H,7H)-DIONE

摘要

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention describes method for preparing 2,2,7,7- tetramethyl-4,9-bis-(dimethylamino)-tetrahydro-1,6,4,9,2,7-dioxadiazadisilecin-5,10(2H, 7H)-dione. Method involves interaction of O-silylurethan of the general formula Me3SiOC(O)NRR', wherein R is hydrogen atom, SiMe3; R' is NMe2 with dimethylchloromethylsilane or its mixture with hexamethyldisilazane at boiling for 30-40 min. EFFECT: simplified process, enhanced yield of end product. 2 ex
