Reaction Conditions:
Stage #1: [2-(3,4-dichlorophenoxy)ethyl]trimethylsilanewith cesium fluoride in N,N-dimethyl-formamide at 60; for 1 h;Inert atmosphere;
Stage #2: with water in N,N-dimethyl-formamide;Inert atmosphere;
Steps:
Procedure of trimethyl silane cleavage
General procedure: To a solution of [2-(phenoxy)-ethyl]-trimethyl-silane (Table-3, entry-1) (195mg, 1.0 mmol) in dry DMF (2 ml) was added cesium fluoride (576 mg, 3.0 mmol) and heated at 60°C for 1 h. Reaction mass was diluted with water and extracted with ethyl acetate (3 x 20 ml). The combined organic layer was washed with water, brine solution, dried over anhydrous sodium sulphate and concentrated under reduce pressure to give phenol 92mg (93% yield). Phenols of Table-3 are commercially available from Aldrich and its identity was confirmed by comparison of 1H NMR data with authentic sample.
