The complexes react with P(OMe)3 giving 1 : 1 adducts which exist in solution in two isomeric forms, both containing a terminal H and a (μ-H) ligand.Both (1) and (2) react with RNC (R = But, Bun, p-MeOC6H4, or p-MeC6H4SO2CH2) to give the complexes (5) containing an NC-bonded formimidoyl ligand.With CH3CN (1) and (2) react to give a major product formulated as > and containing an N-bonded ethylideneimino group; for the product with L-L = dppm this formulation has been confirmed by an X-ray diffraction study.The complex crystallises in the monoclinic space group P21/n with a = 9.765(3), b = 29.940(8), c = 11.813(4) Angstroem, β = 104.69(2) deg, and Z = 4.The structure was solved by a combination of direct methods and Fourier difference techniques, and refined by full-matrix least squares to R = 0.071 for 2614 unique, observed diffractometer data.The minor product obtained in the reaction of (2) with CH3CN is suggested on the basis of spectroscopic evidence to be (7b) containing an NC-bonded acetimidoyl ligand.Both (1) and (2) form an unstable adduct with CO but do not react with HCCH, H2C=CH2, or MeO2CCCCO2Me.
