Procedure
Evaporation of the original chloroform extract, gave colourless crystals (28g). The n.m.r. spectrum of this material indicated the presence of some of the secondary phosphine oxide, 1-oxo-1,2,3,4-tetrahydrophosphinoline. This mixture was again treated with alkaline hydrogen peroxide, and a similar work-up gave a further 25g of crystalline 1-hydroxy-1-oxo-1,2,3,4-tetrahydrophosphinoline, m.p. 142°-4°.
