Steric structure of some ortho-substituted selenoanisoles and their sulfur and oxygen analogs

Abstract

1. All of the studied anisoles and methyl-substituted thio- and selenoanisoles exist preferably in the flat or close to flat s-trans forms. 2. The halo-substituted thio- and selenoanisoles are depicted by almost orthogonal conformations. © 1974 Consultants Bureau.
