stannous octoate; In hexanoic acid; at 135℃; | The reaction was performed in a melt of glycolide using 1.5 equivalents of glycolide with 1 eq. of butanol in the presence of 0.001 Eq of tin catalyst (Tin II ethylhexanoate 90% in hexanoic acid). The reactants were then charged into a vial/round bottom reactor containing a stir bar. The reaction vessel was then sealed and flushed with Nitrogen before being dipped in an oil bath maintained at a temperature around 135C. The reaction was then allowed to run overnight with constant stirring. The next day, the flask was removed from the oil bath and 2-3 ml of dry CHC13 was added to the reaction mixture immediately to prevent the solidification of the melt. The compound was then purified by column chromatography using a silica column and 2% isopropanol + 98% CHC13 as the solvent system. The first two fractions contained the compound. The TLC of the fractions was done using a silica TLC plate and developed by charring with PMA. The solvent was then stripped off from the combined fractions 2 and 3 and the compound was dried in high vacuum overnight. The structure was analyzed by proton NMR and C13 NMR. |
