A mild method for rapid tert-Butyldiphenylsilylation of primary and secondary alcohols

A rapid and efficient method for the protection of primary and secondary alcohols as their tert-butyldiphenylsilyl (tBDPS) ethers was developed. Reaction of the alcohol and tBDPSCl in DMF with AgNO3, NH4NO3, or NH4ClO4 provides good yields of the corresponding silyl ethers.

Amine-free silylation of alcohols under 4-methylpyridine N-oxide-catalyzed conditions

Amine-free silylation of various alcohols catalyzed by 4-methylpyridine N-oxide in the presence of MS4A at room temperature was developed. This simple method gave various silyl ethers in a high yield.

Nonhydrolytic synthesis of silanols by the hydrogenolysis of benzyloxysilanes

The hydrogenolysis of benzyloxysilanes was smoothly catalyzed by Pd/C in THF to give corresponding silanols under nonhydrolytic conditions. The reaction proved to be applicable to various benzyloxysilanes giving silanemonools, diol, and triol.
