SPECIFIC COMPOUNDS - 21 Fluorosilyl group-containing compounds e.g. 8,8-diphenyl-8-silatricyclo(7.4.0.02,7)trideca-1(9),2(7),3,5,10,12-hexaene of formula (I'), fluorodiphenyl(2-phenylphenyl)silane, methyldiphenyl(2-phenylphenyl)silane, 2-(2-(trifluorosilyl)phenyl)pyridine and 2-(2-(2-fluoro-2-silatricyclo(9.4.0.03,8)pentadeca-1(11),3(8),4,6,9,12,14-heptaen-2-yl)phenyl)pyridine, are disclosed.    EXAMPLE - 31 mg 2-Phenylpyridine, 76 mg 1-diethylamino-1-(1,3,2-dioxaborolan-2-yl)-1,1-diphenylsilane and 35 mg potassium fluoride were added to 0.60 mL xylene in argon atmosphere, stirred and heated at 135 degrees C for 15 minutes. 162 mg Potassium peroxodisulfate and 4.4 mmolmg tetrakis(cyanomethyl) palladium(II) bis(tetrafluoroborate) (Pd(NCCH3)4(BF4)2) were added to the reaction mixture, stirred and heated at 135 degrees C for 24 hours. The obtained crude was purified by silica gel column chromatography using hexane and ethyl acetate in ratio of 10:1, to obtain 60 mg 8,8-diphenyl-8-silatricyclo(7.4.0.02,7)trideca-1(9),2(7),3,5,10,12-hexaene.
