The (triphenylmethyl)silanetriol (1) was obtained in good yield by the hydr
olysis of (triphenylmethyl)trichlorosilane, prepared by the Friedel-Crafts
alkylation of benzene with (trichloromethyl)trichlorosilane in the presence
of aluminum chloride, with ice. The single crystal of [1(.)THF] for X-ray
diffraction was grown as colorless in a saturated THF solution. The solid s
tructure of [1(.)THF] was disclosed to be two-dimensional array in head to
head hydrogen-bonding fashion.
