•Mono- and dimethyl(nitrosyl)ruthenium complexes supported by a Tp ligand were prepared.•Use of dimethylzinc as alkylating reagents led to isolation of methyl complexes in good yields.•The dimethyl complex is thermally robust.•Protonolysis of the dimethyl complex with triflic acid resulted in a monomethyl triflato complex.
Reaction of [TpRuCl2(NO)] (1) (Tp = HB(pyrazol-1-yl)3) with dimethylzinc, Zn(Me)2, gave rise to a dimethyl complex [TpRu(Me)2(NO)] (2) and a monomethyl complex [TpRuCl(Me)(NO)] (3) in good yields, while the use of a Grignard reagent, MeMgCl, as the alkylating agents led to isolation of 2 in low yield. Complexes 2 and 3 were confirmed by single-crystal X-ray diffraction analyses. Treatment of 2 with triflic acid, CF3SO3H, afforded a triflato complex [TpRu(Me){OS(O)2CF3}(NO)] (4).
