) or the generated dialkylamine can remain in the metal coordi-
nation sphere (Eq. 6.41

of the bound dialkylamine from adducts of this type can sometimes be difficult.

From Metal Alkoxides
The combination of the greater acidity and the typically lower volatility of phenols
over alcohols allows metal alkoxides to be used as precursor for the synthesis of
corresponding aryloxide derivatives (Eq. 6.43

,
127
).
