“…Nonetheless, clearly present in 6 ·Et 2 O is the formation of a –N PMe 3 group (U1–N6 = 2.115(2) Å; U1–N6–P1 = 161.7(2)°), with metrical parameters comparable to its U–NIm interaction (U1–N3 = 2.141(2) Å; U–N3–C43 = 168.8(2)°) and the U–N PPh 3 bond in Cp 3 UNPPh 3 (U–N = 2.07(2) Å; U–N–P = 172(1)°). 25 We reason that upon formation of the phosphinimide, steric congestion forces structural rearrangement, consequently initiating a cascade of chemical events that gives the complicated product mixture containing 6 . Photolysis in the presence of the more encumbered phosphine, PMe 2 Ph, leads exclusively to the formation of 3 .…”

“…Synthesis of HN=PPh2CH2PPh2PdCI2 (12). A solution of 2 (2.750 g; 5.83 mmol) in dry acetonitrile (25 mL) was added dropwise to a solution of K2PdCl4 (1.905 g; 5.83 mmol) in distilled water (5 mL).…”

“…Almost quantitative yields of 12 were obtained by allowing solutions of 7 or 8 in acetonitrile to interact with methanol at room temperature. Typically, distilled methanol 1,20 mL) was added to a solution of 7 (1.50 g; 2.04 mmol) in acetonitrile (25 mL) and the solution was stirred at room temperature for 4 h before the solvent was then removed in vacuo to give analytically pure 12 in almost quantitative yield. The analytical and spectroscopic data of the product as obtained were in full agreement with those listed above for 12. Crystal Structure Determination of 12. A crystal (0.15 x 0.23 x 0.26 mm) of PdCl2(P(C6H5)2CH2P(C6H5)2NH)-CH2Cl2 was mounted on a Pyrex filament with 5-min epoxy resin.…”

“…Metal-imido multiple bonds have very recently been extended to the actinides, in compounds such as (MeCp)3UNPh71 and Cp3MNPPh3 (M = Th, U). 72 Other metal-ligand multiply bonded units collected at the outset remain attractive subjects for investigations of atom and group transfer reactions. For example, the first instance of nitrogen atom transfer, from a Mnv=N porphyrin to metal(II,IH) porphyrins, has been reported.73 There is also at least one example of what might be termed an alkylidene group transfer reaction.…”
