[Au(PEt3)][PF6]. The reaction of (1) with excess of sulphur in the presence of 1,5-diazabicyclo[5.4.0] undec-5-ene results in PP bond cleavage and formation of a cyclic dithiophosphinic acid. The diphosphene, (1), reacts with LiMe to afford the anion [RP–P(Me)R]–. Quenching with MeOH affords the diphosphine R(H)P–P(Me)R, whilst treatment of [RP–P(Me)R]– with OH– causes P–P bond cleavage and formation

A new stable diphosphene (Me3Si)3CPPC(SiMe3)3 has been isolated and characterized particularly by its NMR data; the 31P NMR chemical shift appears to be the largest ever observed.

Ozonolysis of bis[tris(trimethylsilyl)methyl]diphosphene
Ozonolysis of the diphosphene (1) occurs with a 2 : 1 stoicheiometry (ozone : diphosphene);the reaction carried out at low temperature, gives a relatively stable cyclic diperoxide(2).
