Rearrangement of a phosphorus-carbon-phosphorus bridge to a phosphorus-nitrogen-phosphorus bridge via organogermanium- or organotin-assisted cleavage of a phosphorus-carbon bond. Crystal and molecular structure of the imine salt (CH3)Ph2PNPPh2(NH2) +Cl-

When Me3SiN=PPh2CH2PPh2=NSiMe3 is treated with organogermanium halides in the presence of water, the trimethylsilyl groups are removed and the backbone of the molecule is rearranged to yield quantitatively the imine salt (CH3)Ph2PNPPh2-(NH2) +Cr-. Unassisted hydrolysis gave only the methylene-bridged dioxide Ph2(O)PCH2P(O)Ph2. The imine salt structure (crystal data: triclinic P1, a= 11.034 (3)?, b = 13.724 (3) ?, c = 8.816 (3) ?, α = 99.55 (2)°, β = 109.30 (3)°, γ = 106.15 (2)°, V = 1160.2 ?3, Z = 2; R1 = 0.043 and R2 = 0.052 for 4079 unique reflections) contains a centrosymmetric dimeric hydrogen-bonded pair of cations in which the hydrogens of the NH2 groups of the two cations are associated with two chlorides. The cation structure has a bent (142.9°) P=N=P backbone with short P=N bond lengths (1.57 ?) compared to the longer (1.62 ?) P-N bond for the P-NH2, feature.
