Reaction of PhCHO with Me2CO under H in the presence of Pd/C and NaOH at 80 under 7.0 kg/cm2 gave 81.4% PhCH2CH2COMe, which was treated with MeMgCI in THF at 5 to room temp, to give 76.1% PhCH2CH2CMe2OH.Me2COCHOR:H2, R:NaOH, C:Pd, S:NaOH >OIINOTE:5% Pd/C; pressure 7.0 kg/cm2 and 80 in an autoclave for 7.5 htReactants: 2, Reagents: 2 f Catalysts: 1, Solvents: 1,Steps: 1, Stages: 1Methyl(aroxymethyl)difluorosilanes and their n- and it ・donor properties.Golovanova, N.

The IR spectra of PhOH-l complexes gave a Taft a* value of 1.72 for the SiF2Me group. UV spectra of charge-transfer complexes of 4-XC6H4OCH2R [II; R = SiF2Me, H, Si(OEt)3, SiEt3] with C2(CN)4 were also given.
