WebThe Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol ( alkoxide ). This reaction was developed by Alexander Williamson in 1850. [2] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction. WebEquip a 5-mL conical reaction vial with a stir vane. Take the reaction vial to the hood to obtain 2.0 mL of the reaction solution using the autodispenser on the bottle. Note: Use the correct autodispenser! This two mL of solution contains the reactant, 2-naphthol ( 4 × 1 0 − 4 moles, 0.0576 g), the catalyst, benzyl tri- n-butylammonium chloride (0.124 g), and the …

Mechanism of the Ullmann Reaction. Biaryls are available through coupling of the aryl halide with an excess of copper at elevated temperatures (200 °C). The active species is a copper(I)-compound which undergoes oxidative addition with the second equivalent of halide, followed by ...
WebSynthesis. Silyl enol ethers are generally prepared by reacting an enolizable carbonyl compound with a silyl electrophile and a base, or just reacting an enolate with a silyl electrophile. Since silyl electrophiles are hard and silicon-oxygen bonds are very strong, the oxygen (of the carbonyl compound or enolate) acts as the nucleophile to form a Si-O …
