摘要：

The reactions of α-ester phosphorus ylids with several azides are described together with a kinetic investigation. The two reaction courses, leading either to diazo compounds or to vic-triazoles, are interpreted as proceeding by an addition elimination sequence. The low values of the entropies of activation provide evidence for a concerted addition in the first step of the reaction. © 1969.
