Synthesis of organofluorosilanes

Novel Synthesis of [33P]-(2-Chloroethyl)phosphonic Acid

“…Straightforward transformation of PCl 3 to P(OTMS) 3 by direct reaction with either sodium trimethylsilanolate or hexamethyldisiloxane with the catalysis of a variety of Lewis acids was not satisfactory . The conversion was finally achieved by an indirect approach via first hydrolyzing PCl 3 to phosphorous acid (H 3 PO 3 ) and then converting to P(OTMS) 3 by N , O -bis(trimethylsilyl)acetamide or N , O -bis(trimethylsilyl)trifluoroacetamide (BSTFA) under mild conditions.…”

Chlorodefluorination of Fluoromethanes and Fluoroolefins at a Lewis Acidic Aluminum Fluoride

“…FSiEt 3 was synthesized based on literature [40] . 1 g ACF was suspended in an excess of FSiEt 3 in a Schlenk tube.…”

“…FSiEt 3 was synthesized based on literature. [40] 1 g ACF was suspended in an excess of FSiEt 3 in a Schlenk tube. The reaction mixture was kept at 70 °C for 24 h. The excess of FSiEt 3 was then removed under reduced pressure at room temperature.…”
