Application
(4-Methoxyphenyl)dimethylsilanol can be used:
- As a starting material in the Pd-catalyzed cross-coupling reactions with various aryl halides to obtain biaryl compounds using Cs2CO3 base.
- As a starting material to prepare potassium (4-methoxyphenyl)dimethylsilanolate, which in turn is used to synthesize biaryl derivatives by reacting with aryl bromides.
- As a co-catalyst along with Mo(CO)6 applicable in the 4-decyne metathesis.
