Versuchsvorschrift
DCC (190 mg; 0.92 mmol) in THF (4 ml) is added dropwise over the course of 4 minutes to a solution of the phosphinic acid 1 (270 mg; 0.83 mmol) in dry THF (4 ml) and absolute ethanol (0.30 ml; 5.15 mmol) which is boiling under reflux. After 1.5 hours (check via DC) the reaction solution is cooled to room temperature and filtered. The filtration residue is washed with ether.
