A new thiono-thiolo allylic rearrangement of phosphoro-and phosphonothionates with Pd(PPh3)4 catalyst is described, where a variety of thionates are converted to the corresponding thiolates in excellent yields.

β¦ Synopsis
Palladium(I1) effectively catalyzes the [3,31-sigmatropic type rearrangement of propargyl thionophosphates to provide allenyl thiolophosphates specifically.
Recently we have reported that Pd(0) nicely catalyzes the rearrange-

We recently reported that mercuric trifluoroacetate was an effective catalyst for equilibrating carbamic esters of allylic alcohols at room temperature (1 8 3, X= NMe2). 394 Yields were uniformly high, and side-reactions (elimination, cyclization, &d sk2eta.l rearrangement) occasionally encountered
