A100-mL, one-necked, round-bottomed flaskis fitted with anefficient reflux condenserand arranged for magnetic stirring and heating. The flask is charged with50 mL ofpentaneand2.0 g (13 mmol) ofalcohol. To the rapidly stirred solution is added16 g (180 mmol) of activatedmanganese(IV) oxidein...
To a solution of6-methoxy-3-methylindole(5.0 g,31 mmol) in distilled acetonitrile (150 mL) were added di- tert butyl dicarbonate(7.44 g, 34.1 mmol) andDMAP (0.195 g, 1.6 mmol).The reaction mixture was stirred at rt for 12 h. The solvent was removed underreduced pressure. The residue ...
lsopentane is generally marketed in a compressed liquefied form. Isopentane is used as a solvent, is a building-block chemical used in reactions to form other industrial substances, and has been used in the manufacture of chlorinated derivatives and the production of amyl-naphthalene and isoprene....
