Title compound 1 is sterically shielded to such an extent that many "normal" reactions cannot occur. It is possible, however, to prepare the carboxylic acid 2, its acyl chloride 3 and the oxidation product 4. Furthermore, halogen substitutions to yield 5 and 6 and trialkylstannations to give 8a, b c
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 correlat
