- Transition metal chemistry of main group hydrazides. 5. Functionalization of methylhydrazine with alkyl/alkoxy groups and aryl/aryloxy-substituted phosphorus(V) oxides and sulfides. First examples of bidentate interactions of R2P(E)(NMeNH2) (R = OMe, OEt, OPh, Ph: E = S, O) with Pd(II). X-ray structure of (MeO)2P(S)NMeNH2·PdCl2

The reactions of alkoxy-, aryloxy-, and aryl-substituted phosphorus monochlorides (R2P(E)Cl: R = OCH3, E = S; R = OC2H5, E = S; R = OC6H5, E = O; R = C6H5, E = O) with methyl hydrazine yielded the new monophosphorus hydrazides (R2P(E)NMeNH2: R = OCH3, E = S (1); R = OC2H5, E = S (2), R = OC6H5, E = O (3); R = C6H5, E = O (4)) in good yields. The monophosphorus hydrazides 1-4 reacted smoothly with PdCl2(PhCN)2 at 25°C to give the new cyclopalladaphosphohydrazides R2P(E)NMeNH2·PdCl2 (R = OCH3, E = S (5); R = OC2H5, E = S (6); R = OC6H5, E = O (7); R = C6H5, E = O (8)) in good yields as air-stable crystalline solids. The chemical constitutions of 1-4 and 5-8 were established by complete NMR (1H and 31P) spectroscopic and C, H, N, and Cl analysis data. The structure of 5 was further confirmed by X-ray diffraction study. Crystal data for 5: monoclinic, space group C2/c, with a = 25.029(9) A?, b = 10.2800(10) A?, c = 9.167(3) A?, β = 104.750(10)°, and Z = 8. The structure was solved by direct methods and was refined to R = 0.035.
