The identification of some new mixed‐valence phosphorus thiohalides in solution

Abstract

Abstract The reaction of a phosphorus trihalide PX 3 (X = Cl, Br, or I) with a thiophosphorus halide P(S)Y 3 (Y = Cl or Br) in the presence of zinc powder as a halogen acceptor has led to the formation of several new mixed‐valence phosphorus species in solution. These include examples with two or three phosphorus atoms present, such as Y 2 P(S)PX 2 and Y 2 P(S)P(X)P(S)Y 2 , or halogen exchange derivatives thereof. Structural assignments for these species have been made on the basis of 31 P NMR shift, multiplicity, intensity, and coupling constant data. © 2010 Wiley Periodicals, Inc.
