Versuchsvorschrift

2-Diisopropylaminoethyl Tributylstannyl Ether is prepared from 89.4 gm (0.15 mole) bis(tributyltin) oxide and 43.5 gm (0.30 mole) 2-diisopropylaminoethanol in 200 ml benzene. This is stirred and heated to reflux in a system that contains a Dean-Starke tube. After refluxing for 23 hours a total of 2.6 ml of water (theory 2.7 ml) had collected in the Dean-Starke tube. Solvent is stripped off on a rotating evaporator to provide 134.3 gm of orange liquid. This is fractionated at reduced pressure with collection at 147°-155° C. at 0.4 mm of 87.6 gm of straw liquid (Percent theory - 73). Infrared spectral analysis shows this liquid to be the desired ether.
