    • Depending on the precise work-up procedure the amino-silanols e.g. 4 were often contaminated with the ring closed form e.g. 30. Chromatography on silica, or Kugelrohr distillation gave mostly or exclusively the closed form (stirring in water reversed the process). Oxygen linked systems were always isolated in the cyclic-siloxane form. (Chemical Equation Presented)

    • For the oxazolines trans- and cis-6a and -6b the stereochemical assignment was clear from the coupling constant between the two CHMe protons. For trans- and cis-6a it is 9.9 and 3.3 Hz, for 6b 9.6 and 1.8 Hz, and for the known parent 2,3-dimethyloxazoline (6, R = H) 10 and 3.5 Hz respectively (Fisyuk, A. S.; Ryzhiva, E. V.; Unkovskii, B. V. Chem. Hetero. Comp. 1994, 30, 238).

    • Generally the only alkenes which add efficiently are ethylene, stilbenes, and strained cyclic alkenes (norbornene, cyclopentene). Erker, G.; Kropp, K. J. Am. Chem. Soc. 1979, 101, 3660.
