摘要：

[PhCNSSN]2 reacts under mild conditions with molecules containing bonds of the types P-Cl (Ph2PCl and PhPCl2), Si-Br (Me3SiBr) and activated C-Cl or C-Br (ortho-chloranil or MeCOBr) with the formation of [PhCNSSN]X (X = Cl or Br) and the corresponding E-E (E = P, Si or C) bonded compounds; the application of dithiadiazolyl radicals as coupling reagents is discussed in the context of the strength of the E-Hal bond.
