✦ Synopsis

The 'H, I3C and =Si nuclear magnetic resonance spectra of the parent compound and twelve derivatives of 2,8,9-trioxa-5-aza-l-silatri~yclo[3.3.3.O~~~]undecane (silatrane) are discussed. Effective Taft polarity constants for the silatrane snbstituents are proposed. An equation is developed to correlate the "Si NMR chemical shifts of the silatranes with the corresponding organo-triethoxysilanes.
