Abstract

(57%)(q, SiCH3), 2.3 (9, SiCH3), 15.0 (q, OCCH3), 27.2 (t, norbornyl CHI), 27.4 (t, norbornyl CH3, 40.5 (d, norbornyl CH), 58.9 (s, SiCC02Et), 62.2 (t, OCH2), 113.8 (s, SiOC), 164.7 (s, C= O); IR (NaCI) v (C0, Et) 1560 cm-'. Anal. Calcd for C16H3003Si~: C, 58.84; H, 9.25. Found: C, 58.47; H, 9.20. An unusual chemical shift of I3C at C3 (1 13.8 ppm) and an abnormal stretching vibration of the ester carbonyl (1560 cm-l) were observed. These ...
