Abstract

Sterically protected (E,E)‐3,4‐bis(2,4,6‐tri‐t‐butylphenylphosphinidene)dialkylcyclobutenes were isomerized to the corresponding (E,Z) derivatives in the presence of catalytic amounts of iodine. Similar iodine‐induced isomerizations were observed in the case of (E)‐ and (Z)‐2‐phenyl‐1‐(2,4,6‐tri‐t‐butylphenyl)‐1‐phosphaethenes.
