Reactions of diethylzinc with dihydric phenols such as pyrocatechol and saligenin in a molar ratio of 1/1 yield zinc pyrocatecholate and ethylzinc 2-hydroxymethylphenoxide, whereas a molar ratio of 3/2 gives zinc bis(2-ethylzincoxyphenoxide) and zinc bis(2-ethylzincoxyphenylmethoxide). respectively.The latter ethylzincoxygen compounds, containing zinc diphenoxide - or zinc dimethoxide - units complexed internally by ethylzinc groups, form monomeric species in 1,4-dioxane.
