| Abstract: | The earlier unknown Si-fluorinated 2,8-dioxa-5-chalcogenosilocanes RFSi(OCH2CH2)2Y (R = Ph, F; Y = O, S) were synthesized. According to calculations, there is a weak transannular coordinate interaction Y→Si
(Y = O, S), which is much weaker than that in the isostructural quasisilatranes (Y = N). At low temperatures, 1,1-difluoro-2,5,8-trioxasilocane
forms a dimer, in which two molecules of the monomer are linked by four fluorine bridges Si-F→Si located in pairs in the two
orthogonal planes SiF2Si. |
