Synthesis and characterization of stable (triphenylmethyl)silanetriol

Abstract

The (triphenylmethyl)silanetriol (1) was obtained in good yield by the hydrolysis 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 structure of [1(.)THF] was disclosed to be two-dimensional array in head to head hydrogen-bonding fashion.
