A new pathway for the synthesis of 1,3-dioxa-6-aza-2-germacyclooctanes: molecular structure of 2,2-di(2-thienyl)-6-methyl-1,3-dioxa-6-aza-2-germacyclooctane
摘要:
A novel reaction pathway has been applied for the synthesis of 1,3-dioxa-6-aza-2-germacyclooctanes. Compounds of this type were obtained by the dehydrocondensation of di(2-thienyl)germane and diethanolamines without a catalyst. The molecular structure of 2,2-di(2-thienyl)-6-methyl-1,3-dioxa-5-azacyclooctane has been determined by X-ray diffraction study. The interatomic N --> Ge distance of 2.446 Angstrom indicates the presence of a weak transannular bond.
