Silanetriols With Bulky Aryl Substituent 2,4,6-Triisopropylphenylsilanetriol

Similarly to those with bulky alkyl substituents, silanetriols with bulky aryl groups can be synthesized and isolated without problems. Thus 2,4,6-triisopropylphenylsilanetriol, or TipSi(OH)3, was readily prepared by the hydrolysis of TipSiCla in 70% yield (1). Although with bulky Tip group, this compound showed no restricted rotation and and C-NMR spectra exhibited sharp 

Obtained triisopropylphenylsilanetriol is an air-stable white solid and can be stored for a long time.
