Dipole moments, structure, and transannular interactions in silatranes containing planar fragments

This is the authors' abstract. We don't add key points for this paper.

The method of dipole moments and theoretical calculations (DFT B3LYP/6-31G * ) were used for structural assessment of silatranes N[CH 2 (RMeC 6 H 2 )O] 3 SiR 1 containing planar fragments in the six-membered semirings. They are endo structures with transannular N→Si interaction which involves, along with nitrogen and silicon, oxygen atoms adjacent to silicon.
