The reaction of Ph2P(NSiMe3)[N(SiMe3)2] with RSeCl3(R = Ph, Me, Et) in acetonitrile produces 1,5-Ph4P2N4Se2R2[R = Ph, (1a); Me, (1b); Et, (1c)] and 1,5-Ph4P2N4Se2, (2a) when R = Me or Et; X-ray crystallography shows that (1b) is an eight-membered chair with the two selenium atoms displaced on either side of the P2N4 plane by 1.073(2)Å.
Ph 2 P(NSiMe 3)[N(SiMe 3)2 ]与RSeCl 3(R = Ph,Me,Et)在乙腈中的反应生成1,5-Ph 4 P 2 N 4 Se 2 R 2 [R = Ph,(1a); 我(1b); Et,(1c)]和1,5-Ph 4 P 2 N 4 Se 2,(2a),当R = Me或Et时;X射线晶体学表明(1b)是一个八元椅子,其中两个硒原子在P的两侧移位2 N 4平面乘1.073(2)Å。

treatment of Ph2PN2(SiMe3)3 with a mixture of SeCl4 and Se2Cl2 in acetonitrile, with [PtCl2(PEt3)]2 gives the adducts [PtCl2(PEt3)]n[η1-N-Ph4P2N4Se2](2, n- 1; 3, n- 2) in which the P2N4Se2 ring is shown by an X-ray structural determination of 3 to contain a transannular Se–Se interaction; the oxidative addition of 1 or 2 to Pt(C2H4)(PPh3)2 produces the corresponding η2-Se,Se′ complexes.
