Abstract

AbstractThe reaction of a phosphorus trihalide PX3 (X = Cl, Br, or I) with a thiophosphorus halide P(S)Y3 (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 Y2P(S)PX2 and Y2P(S)P(X)P(S)Y2, or halogen exchange derivatives thereof. Structural assignments for these species have been made on the basis of 31P NMR shift, multiplicity, intensity, and coupling constant data. © 2010 Wiley Periodicals, Inc.
