Abstract:
1. The conformational equilibrium, chair (e)-twist, which is anancomerically shifted toward the chair form for R=C(CH3)3, is characteristic for 2-benz[e]-1,3-dioxepanes, where R=H, CH3, C2H5, n-C3H7, and i-C3H7. 2. A correlation between the μ2 of the 2-alkyl-1,3-dioxanes and the induction constants σI was found. © 1980 Plenum Publishing Corporation.
