“…The Ru1–N1 (1.7991(14) Å) and N1–N2 (1.163(2) Å) bond distances are also similar to those of [RuCl 3 ( p -NNC 6 H 4 Me)(PPh 3 ) 2 ] (Ru–N, 1.784(5) Å; N–N, 1.158(6) Å). However, similar piano-stool type aryldiazenido complexes, [CpRu(NNC 6 H 4 OMe)(PPh 3 ) 2 ](BF 4 ) 2 (Ru–N–N, 175.4(3)°; N–N–C, 158.9(4)°) and [TpRu(NNC 6 H 5 ){P(OEt) 3 } 2 ] 2+ (Ru–N–N, 178.212°; N–N–C, 171.330°), show a near-linear arrangement of the Ru-bonded N 2 Ar ligand. Their total charge of 2+ should account for these differences.…”

Nitrosation of anilines at the ortho position was found to proceed on a ruthenium hydridotris(pyrazolyl)borato (Tp) complex. Reactions of [TpRuCl2(NO)] (1) with primary anilines 4-NH2C6H4R (R = tBu, H) in the presence of excess Et3N in CH2Cl2 gave amine-chelated nitrosoarene complexes [TpRuCl{N(O)–C6H3R–NH2-κ2 N,N}] (R = tBu (2a), H (2b)). Use of 2,4,6-trimethylaniline afforded an aryldiazenido complex [TpRuCl2{NNC6H2(Me)3}] (3) without forming the nitrosation product because of the introduction of the Me substituents at the ortho positions. On the other hand, in the case of secondary amines (N-methylanilines 4-NH(Me)C6H4R (R = tBu, H)), similar reactions gave amine-chelated nitroso complexes [TpRuCl{N(O)–C6H3R–NHMe-κ2 N,N}] (R = tBu (4a), H (4b)) and imine-chelated nitroso complexes [TpRuCl{N(O)–C6H3R–NCH2-κ2 N,N}] (R = tBu (5a), H (5b)). Conversion of 4b into 5b by O2 was disclosed by 1H NMR monitoring. Moreover, oxidative reaction of 2a afforded an amide-chelated nitroso complex [TpRuCl{N(O)–C6H3(tBu)–NH-κ2 N,N}] (6a) through one-proton release from the NH2 group.
