✦ Synopsis

~ujii et al. (1) have recently published the results of their work on the reaction between triethyl phosphite and bromo-and chloroacetglenes.

We now communicate the results of our own studies on this reaction which we have referred to on a previous occasion (2).

Gur approach is somewhat different and our results, obtained under different conditions, also differ somewhat from those of F'ujii et al.
