Synthesis method

1. In a 250 ml Erlenmeyer flask equipped with a magnetic stirrer and a nitrogen introduction tube, place 27.9 g (0.1 mol) of triphenyl chloride and 100 ml Thousand dry benzene. The mixture was stirred under dry nitrogen until a clear solution formed. Cool the solution to 0°C in an ice-salt bath. Add 13.4 grams (0.1 mol) of anhydrous monodimethyl ether tetrafluoroborate complex through the dropping funnel within 10 minutes, and continue stirring for 1 minute without further cooling. 50 ml of petroleum ether was added to the reaction mixture, and filtered through a glass core funnel. The bright yellow solid was washed with two 50 ml portions of petroleum ether, dried under a stream of dry nitrogen and then in vacuo. Get 2 grams (73%, melting point is about 200°C (decomposition).

Purpose

1. Same as trityl perchlorate, but more stable, so it is used more often. Alcohol oxidizing agent. Synthesis of alkenes.
