, p. 97 - 100 (1984)
Dynamic NMR study on 9-(2-alkylphenoxy)-1,4-dimethyltriptycenes revealed that when the o-alkyl group is methyl or isopropyl, two conformers, ap and +/-sc, are separately observed at room temperature and that the interconversion between them occurs by gear
Restricted Rotation Involving the Tetrahedral Carbon. LVII. Stereodynamics of 9-(2-Alkylphenoxy)-1,4-dimethyltriptycenes
Yamamoto, Gaku,Oki, Michinori
, p. 1953 - 1961 (2007/10/02)
1,4-Dimethyl-9-phenoxytriptycene and its derivatives carrying a methyl, isopropyl, or t-butyl group in the o-position of the phenoxyl moiety were synthesized and their dynamic NMR behavior was studied.These molecules are considered to constitute a bevel g
