الإجراء التجريبي

Tri-n-butyl phosphine (20.27 g, 25 ml, 0.1 mole) was added dropwise to a rapidly stirred solution of 2-chloropropanoic acid (10.85 g, 9.1 ml, 0.1 mole) in 31 ml of acetone. The reaction was, of course, exothermic, and the addition of the phosphine was maintained at a rate such that the temperature did not exceed about 35° C. After the addition was complete, the acetone solvent was removed under reduced pressure leaving a viscous liquid having an infrared spectrum and elemental analysis corresponding to the formula ##STR13##
