Two new heterocyclic and one acyclic species were prepared by reduction/deselenation of the five‐membered heterocycle PhP(Se)CH 2 PhP(Se)Se 2 (containing a PCPSe 2 ring sequence). Deselenation with Me 3 SiCN led to the four‐membered heterocycle PhP(Se)CH 2 PPh(Se)Se (containing a PCPSe ring sequence), whereas reaction with Bu 3 P afforded the five‐membered heterocycle PhP(Se)CH 2 PhP(Se)SePPh (ring sequence PCPSeP) and reduction with K metal afforded the dipotassium salt of methylene‐bis(diselenophenylphosphinic) acid [K 2 (PhPSe 2 ) 2 CH 2 ]. The new compounds were characterised by a combination of NMR, MS and FT IR spectroscopic techniques; their structures were confirmed by single crystal X‐ray analyses. (© Wiley‐VCH Verlag GmbH & Co.
