Radicalcyclizations of acylsilanes with radicalphilic pendant introduced on silicon proceeded in a tandem fashion to give spiro products containing a cyclic silyl ether skeleton. Because the alkoxysilyl group can be replaced with a hydroxy group through oxidation, the spiro silyl ethers can be converted into diols. In the case with a radical intermediate carrying 2-oxa-3-sila-6-heptenyl skeleton,
(Chloromethyl)dimethylsilanol was synthesized by the hydrolysis of (chloromethyl)dimethylchlorosilane, N-[(chloromethyl)dimethylsilyl]amines, or N-(chloromethyl)dimethylsilyl-N-methylamide of diisopropylphosphoric acid.
