Yield:637-50-3 97%

Reaction Conditions:

with aluminum (III) chloride;triphenylphosphine in nitromethane at 80; for 2 h;Reagent/catalyst;

Steps:

2.2. A typical alcohol dehydration procedure
General procedure: In a typical reaction, alcohol (0.4 mmol) was mixed with AlCl3 (0.02 mmol, 5 mol%) and triphenylphosphine (PPh3, 0.02 mmol, 5 mol%) in nitromethane (1.0 mL). Thereafter the mixture was stirred at 80 °C for 2 h. After the reaction, the mixture was cooled to room temperature, and the product was isolated using preparative thin layer chromatography (TLC, eluting solution: petroleum ether/ethyl acetate, 5/1 (v/v)). Tests for substrate scope were all performed with an analogous procedure.
