E. Lukevics et al., A NEW PATHWAY FOR THE SYNTHESIS OF 1,3-DIOXA-6-AZA-2-GERMACYCLOOCTANES - MOLECULAR-STRUCTURE OF IENYL)-6-METHYL-1,3-DIOXA-6-AZA-2-GERMACYCLOOCTANE, Journal of organometallic chemistry, 523(1), 1996, pp. 41-45
A novel reaction pathway has been applied for the synthesis of 1,3-dio
xa-6-aza-2-germacyclooctanes. Compounds of this type were obtained by
the dehydrocondensation of di(2-thienyl)germane and diethanolamines wi
thout a catalyst. The molecular structure of -di(2-thienyl)-6-methyl-1
,3-dioxa-5-azacyclooctane has been determined by X-ray diffraction stu
dy. The interatomic N --> Ge distance of 2.446 Angstrom indicates the
presence of a weak transannular bond.
