Experiment 2.13.: Micro-Scale Synthesis Of Triphen

Experiment 2.13.: Micro-scale Synthesis of Triphenylmethanol Aim: This was a two turn on off try out in which the aim of the first pct was to compound the Grignard reagent phenylmagnesiumbromide from reacting bromobenzene with magnesium and diethyl ether. The aim of the second part was to synthesise the intoxicant triphenylmethanol using the previously produced phenylmagnesiumbromide by reacting it with benzophenone. Introduction: This experiment touch two reactions. First the Grignard reagent, phenylmagnesiumbromide, was synthesised from bromobenzene, magnesium and diethyl ether. Once produced, the Grignard reagent was so employ to synthesise triphenylmethanol by reacting it with benzophenone. Using a Grignard reagent is a utile way of synthesising an alcohol from a ketone. Ketones yield 3rd alcohols so the alcohol produced in this reaction is a ordinal one. reaction Scheme: Procedure: The procedure outlined in the chemistry Laboratory Manual Results : green goddess of consummate(a) produce: 0.83g stomach of gross(a) harvest-feast: 0.04g voice yield of pure product: 5% Melting point of pure product: 164.2°C Rf value: Benzophenone: 69% Crude product: 88% Pure product: Nothing was seen under the UV calorie-free TLC didnt work on it.
