This method has been used to produce a variety of homoleptic aryloxide complexes
and has also been applied to the synthesis of mixed alkyl, aryloxide derivatives of
metals. Partial substitution is typically achieved by simple control of the stoichiometry
or by using sterically demanding aryloxides (Eqs 6.49,
133
,
134
6.50,
135
and 6.51
136
).
