## Abstract 250 MHz ^1^H NMR of two monosubstituted [2.2]paracyclophanes shows that whether the substituent is an electron releasing group, OMe, or a withdrawing group, CO~2~Me, the transannular effect is deshielding. 62.86 MHz ^13^C NMR shows that among the six transannular effects, only one has a

The 'H and -C NMR spectra of a series of 1,3,2-dioxarsolanes have been obtained at 2.1T and some at 9.4T. The chemical shifts and spin-spii coupling constants have been obtained from complete spectral analyw of the 'H and proton-coupled -C spectra. The spectral data are interpreted on the basis of t

## Abstract The ^1^H NMR spectra of E/Z 2‐hydroxyindolenines are reported in both CDCl~3~ and DMSO‐d~6~ solvents. The data suggest a preferred conformation of the heterocyclic ring, which is slightly distorted from planarity, in agreement with the x‐ray crystallographic data of one of the isomers.
